misc: mei: client.c: fix problem of return '-EOVERFLOW' in mei_cl_write

2023-11-27T13:38:29+00:00

Clang static analyzer complains that value stored to 'rets' is never
read.Let 'buf_len = -EOVERFLOW' to make sure we can return '-EOVERFLOW'.

misc: mei: client.c: return negative error code in mei_cl_write

2023-11-27T13:38:29+00:00

mei: me: emit error only if reset was unexpected

2023-10-18T08:01:34+00:00

GSC devices perform legal firmware initiated resets due to state transition
that may appear as unexpected to the driver. Lower the log level for those
devices to debug level and save the firmware status registers.
When the device comes out of the reset it is possible to check whether the
resets was due to a firmware error or an exception
and only than produce a warning.
