+
+commit 23bc6ab0a0912146fd674a0becc758c3162baabc upstream.
+
+When we retrieve imtu value from userspace we should use 16 bit pointer
+cast instead of 32 as it's defined that way in headers. Fixes setsockopt
+calls on big-endian platforms.

+Subject: hp-wmi: Fix wifi cannot be hard-unblocked
+
+From: Alex Hung <alex.hung@canonical.com>
+
+commit fc8a601e1175ae351f662506030f9939cb7fdbfe upstream.
+
+Several users reported wifi cannot be unblocked as discussed in [1].
+This patch removes the use of the 2009 flag by BIOS but uses the actual
+WMI function calls - it will be skipped if WMI reports unsupported.

+Subject: s5p-mfc: Add release callback for memory region devs
+
+From: Javier Martinez Canillas <javier@osg.samsung.com>
+
+commit 6311f1261f59ce5e51fbe5cc3b5e7737197316ac upstream.
+
+When s5p_mfc_remove() calls put_device() for the reserved memory region
+devs, the driver core warns that the dev doesn't have a release callback:
+
+WARNING: CPU: 0 PID: 591 at drivers/base/core.c:251 device_release+0x8c/0x90
+Device 's5p-mfc-l' does not have a release() function, it is broken and must be fixed.
+
+Also, the declared DMA memory using dma_declare_coherent_memory() isn't
+relased so add a dev .release that calls dma_release_declared_memory().

+Subject: s5p-mfc: Set device name for reserved memory region devs
+
+From: Javier Martinez Canillas <javier@osg.samsung.com>
+
+commit 29debab0a94035a390801d1f177d171d014b7765 upstream.
+
+The devices don't have a name set, so makes dev_name() returns NULL which
+makes harder to identify the devices that are causing issues, for example:
+
+WARNING: CPU: 2 PID: 616 at drivers/base/core.c:251 device_release+0x8c/0x90
+Device '(null)' does not have a release() function, it is broken and must be fixed.
+
+And after setting the device name:
+
+WARNING: CPU: 0 PID: 591 at drivers/base/core.c:251 device_release+0x8c/0x90
+Device 's5p-mfc-l' does not have a release() function, it is broken and must be fixed.
