Subject: [media] s5p-jpeg: fix system and runtime PM integration
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=3b92fed5e3d6ee7508ca4a3dac10a95a386a3fa5;p=openwrt%2Fstaging%2Fblogic.git

[media] s5p-jpeg: fix system and runtime PM integration

Use generic helpers instead of open-coding usage of runtime PM for system
sleep PM, which was potentially broken for some corner cases.
