From: Daniel Lezcano Date: Mon, 3 Oct 2022 09:26:01 +0000 (+0200) Subject: thermal/intel/int340x: Replace parameter to simplify X-Git-Tag: microblaze-v6.6~1132^2~16^2~1^2^2~9 X-Git-Url: http://git.monstr.eu/?a=commitdiff_plain;h=0d2d586a86e85f10bd8fe47c219024b14de280b8;p=linux-2.6-microblaze.git thermal/intel/int340x: Replace parameter to simplify In the process of replacing the get_trip_* ops by the generic trip points, the current code has an 'override' property to add another indirection to a different ops. Rework this approach to prevent this indirection and make the code ready for the generic trip points conversion. Actually the get_temp() is different regarding the platform, so it is pointless to add a new set of ops but just create dynamically the ops at init time.
