+Subject: ASoC: sgtl5000: Fix VAG power-on handling
+
+From: Sebastian Reichel <sebastian.reichel@collabora.com>
+
+[ Upstream commit aa7812737f2877e192d57626cbe8825cc7cf6de9 ]
+
+As mentioned slightly out of patch context in the code, there
+is no reset routine for the chip. On boards where the chip is
+supplied by a fixed regulator, it might not even be resetted
+during (e.g. watchdog) reboot and can be in any state.
+
+If the device is probed with VAG enabled, the driver's probe
+routine will generate a loud pop sound when ANA_POWER is
+being programmed. Avoid this by properly disabling just the
+VAG bit and waiting the required power down time.

+Subject: net: bcmgenet: suppress warnings on failed Rx SKB allocations
+
+From: Doug Berger <opendmb@gmail.com>
+
+[ Upstream commit ecaeceb8a8a145d93c7e136f170238229165348f ]
+
+The driver is designed to drop Rx packets and reclaim the buffers
+when an allocation fails, and the network interface needs to safely
+handle this packet loss. Therefore, an allocation failure of Rx
+SKBs is relatively benign.
+
+However, the output of the warning message occurs with a high
+scheduling priority that can cause excessive jitter/latency for
+other high priority processing.
+
+This commit suppresses the warning messages to prevent scheduling
+problems while retaining the failure count in the statistics of
+the network interface.

+When asking the ARL to read a MAC address, we will get a number of bins

+states:
+
+- all bins are full, we have no space left, and we can either replace an
+ existing address or return that full condition
+
+- the MAC address was found, then we need to return its bin index and
+ modify that one, and only that one
+
+- the MAC address was not found and we have a least one bin free, we use
+ that bin index location then
+
+The code would unfortunately fail on all counts.

+Subject: net: stmmac: Fix sub-second increment
+
+From: Julien Beraud <julien.beraud@orolia.com>
+
+[ Upstream commit 91a2559c1dc5b0f7e1256d42b1508935e8eabfbf ]
+
+In fine adjustement mode, which is the current default, the sub-second
+ increment register is the number of nanoseconds that will be added to
+ the clock when the accumulator overflows. At each clock cycle, the
+ value of the addend register is added to the accumulator.
+ Currently, we use 20ns = 1e09ns / 50MHz as this value whatever the
+ frequency of the ptp clock actually is.
+ The adjustment is then done on the addend register, only incrementing
+ every X clock cycles X being the ratio between 50MHz and ptp_clock_rate
+ (addend = 2^32 * 50MHz/ptp_clock_rate).
+ This causes the following issues :
+ - In case the frequency of the ptp clock is inferior or equal to 50MHz,
+ the addend value calculation will overflow and the default
+ addend value will be set to 0, causing the clock to not work at
+ all. (For instance, for ptp_clock_rate = 50MHz, addend = 2^32).
+ - The resolution of the timestamping clock is limited to 20ns while it
+ is not needed, thus limiting the accuracy of the timestamping to
+ 20ns.
+
+ Fix this by setting sub-second increment to 2e09ns / ptp_clock_rate.
+ It will allow to reach the minimum possible frequency for
+ ptp_clk_ref, which is 5MHz for GMII 1000Mps Full-Duplex by setting the
+ sub-second-increment to a higher value. For instance, for 25MHz, it
+ gives ssinc = 80ns and default_addend = 2^31.
+ It will also allow to use a lower value for sub-second-increment, thus
+ improving the timestamping accuracy with frequencies higher than
+ 100MHz, for instance, for 200MHz, ssinc = 10ns and default_addend =
+ 2^31.
+
+v1->v2:
+ - Remove modifications to the calculation of default addend, which broke
+ compatibility with clock frequencies for which 2000000000 / ptp_clk_freq
+ is not an integer.
+ - Modify description according to discussions.

+Subject: net: systemport: suppress warnings on failed Rx SKB allocations
+
+From: Doug Berger <opendmb@gmail.com>
+
+[ Upstream commit 3554e54a46125030c534820c297ed7f6c3907e24 ]
+
+The driver is designed to drop Rx packets and reclaim the buffers
+when an allocation fails, and the network interface needs to safely
+handle this packet loss. Therefore, an allocation failure of Rx
+SKBs is relatively benign.
+
+However, the output of the warning message occurs with a high
+scheduling priority that can cause excessive jitter/latency for
+other high priority processing.
+
+This commit suppresses the warning messages to prevent scheduling
+problems while retaining the failure count in the statistics of
+the network interface.

+
+[ Upstream commit e461bc9f9ab105637b86065d24b0b83f182d477c ]
+
+Sed broke on some strings as it used colon as a separator.
+I made it more robust by using \001, which is legit POSIX AFAIK.
+
+E.g. ./config --set-str CONFIG_USBNET_DEVADDR "de:ad:be:ef:00:01"
+failed with: sed: -e expression #1, char 55: unknown option to `s'

+Subject: selftests/ipc: Fix test failure seen after initial test run
+
+From: Tyler Hicks <tyhicks@linux.microsoft.com>
+
+[ Upstream commit b87080eab4c1377706c113fc9c0157f19ea8fed1 ]
+
+After successfully running the IPC msgque test once, subsequent runs
+result in a test failure:
+
+ $ sudo ./run_kselftest.sh
+ TAP version 13
+ 1..1
+ # selftests: ipc: msgque
+ # Failed to get stats for IPC queue with id 0
+ # Failed to dump queue: -22
+ # Bail out!
+ # # Pass 0 Fail 0 Xfail 0 Xpass 0 Skip 0 Error 0
+ not ok 1 selftests: ipc: msgque # exit=1
+
+The dump_queue() function loops through the possible message queue index
+values using calls to msgctl(kern_id, MSG_STAT, ...) where kern_id
+represents the index value. The first time the test is ran, the initial
+index value of 0 is valid and the test is able to complete. The index
+value of 0 is not valid in subsequent test runs and the loop attempts to
+try index values of 1, 2, 3, and so on until a valid index value is
+found that corresponds to the message queue created earlier in the test.
+
+The msgctl() syscall returns -1 and sets errno to EINVAL when invalid
+index values are used. The test failure is caused by incorrectly
+comparing errno to -EINVAL when cycling through possible index values.
+
+Fix invalid test failures on subsequent runs of the msgque test by
+correctly comparing errno values to a non-negated EINVAL.

+Subject: wimax/i2400m: Fix potential urb refcnt leak
+
+From: Xiyu Yang <xiyuyang19@fudan.edu.cn>
+
+[ Upstream commit 7717cbec172c3554d470023b4020d5781961187e ]
+
+i2400mu_bus_bm_wait_for_ack() invokes usb_get_urb(), which increases the
+refcount of the "notif_urb".
+
+When i2400mu_bus_bm_wait_for_ack() returns, local variable "notif_urb"
+becomes invalid, so the refcount should be decreased to keep refcount
+balanced.
+
+The issue happens in all paths of i2400mu_bus_bm_wait_for_ack(), which
+forget to decrease the refcnt increased by usb_get_urb(), causing a
+refcnt leak.
+
+Fix this issue by calling usb_put_urb() before the
+i2400mu_bus_bm_wait_for_ack() returns.
