[PATCH 0/1][SRU][B] Stop thermal messages spamming the kernel log

[Colin King]

From: Colin Ian King <colin.king at canonical.com>

== SRU Justification Bionic/Disco ==

proc_thermal messages are spamming the kernel log when used in
conjunction with thermal. This is because the message is not
set at the correct kernel log level.

NOTE: Bionic SRU backport needed pathname modification because the
driver is in a different location.

== Fix ==

Upstream fix 44c0c23725a16c8803b8809b87651405e8741e4d ("drivers:
thermal: processor_thermal: Downgrade error message"). This is in
5.2 so not applicable for Eoan.

== Test case ==

Without the fix the kernel log is being spammed periodically with
messages in the form:

[ 11.520358] proc_thermal 0000:00:00.1: Unsupported event [0x91]
[ 16.532358] proc_thermal 0000:00:00.1: Unsupported event [0x91]
[ 21.572719] proc_thermal 0000:00:00.1: Unsupported event [0x91]
[ 26.580855] proc_thermal 0000:00:00.1: Unsupported event [0x91]

With the fix these messages are no longer appearing.

== Regression Potential ==

This changes the log level, so regression potential is very limited,
unless some program is relying on this message for some particular
reason.
