ASoC: codecs: rt700/rt711/rt711-sdca: resume bus/codec in .set_jack_detect

The .set_jack_detect() codec component callback is invoked during card
registration, which happens when the machine driver is probed.

The issue is that this callback can race with the bus suspend/resume,
and IO timeouts can happen. This can be reproduced very easily if the
machine driver is 'blacklisted' and manually probed after the bus
suspends. The bus and codec need to be re-initialized using pm_runtime
helpers.

Previous contributions tried to make sure accesses to the bus during
the .set_jack_detect() component callback only happen when the bus is
active. This was done by changing the regcache status on a component
remove. This is however a layering violation, the regcache status
should only be modified on device probe, suspend and resume. The
component probe/remove should not modify how the device regcache is
handled. This solution also didn't handle all the possible race
conditions, and the RT700 headset codec was not handled.

This patch tries to resume the codec device before handling the jack
initializations. In case the codec has not yet been initialized,
pm_runtime may not be enabled yet, so we don't squelch the -EACCES
error code and only stop the jack information. When the codec reports
as attached, the jack initialization will proceed as usual.

USB: gadget: Fix double-free bug in raw_gadget driver

Re-reading a recently merged fix to the raw_gadget driver showed that
it inadvertently introduced a double-free bug in a failure pathway.
If raw_ioctl_init() encounters an error after the driver ID number has
been allocated, it deallocates the ID number before returning.  But
when dev_free() runs later on, it will then try to deallocate the ID
number a second time.

Closely related to this issue is another error in the recent fix: The
ID number is stored in the raw_dev structure before the code checks to
see whether the structure has already been initialized, in which case
the new ID number would overwrite the earlier value.

The solution to both bugs is to keep the new ID number in a local
variable, and store it in the raw_dev structure only after the check
for prior initialization.  No errors can occur after that point, so
the double-free will never happen.

Egress VID for layer 2 multicast is determined from two tables, the MPE
and PGT tables. The MPE table is a two dimensional table indexed by local
port and SMPE index, which should be thought of as a FID index.

In Spectrum-1 the SMPE index is derived from the PGT entry, whereas in
Spectrum-2 and newer ASICs the SMPE index is a FID attribute configured
via the SFMR register.

The validity of the SMPE index in SFMR is influenced from two factors:
1. FID family. SMPE index is reserved for rFIDs, as their flooding is
   handled by firmware.
2. ASIC generation. SMPE index is always reserved for Spectrum-1.

As such, the validity of the SMPE index should be an attribute of the FID
family and have different arrays of FID families per-ASIC type.
