From: Hans de Goede Date: Mon, 14 Nov 2022 15:44:49 +0000 (+0000) Subject: media: atomisp: Remove duplication between runtime-pm and normal-pm code X-Git-Tag: v6.6.17~5419^2~207 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=6736a68fe15640e007a75f873cec86bdf9cc47a6;p=platform%2Fkernel%2Flinux-rpi.git media: atomisp: Remove duplication between runtime-pm and normal-pm code atomisp_suspend() contains a 1:1 copy of atomisp_runtime_suspend() and the same goes for the resume() functions. Rename the runtime functions to atomisp_power_on()/_off() and use these as runtime-pm handlers as well as helper in other places to remove the code duplication.
