Subject: [media] exynos4-is: Do not use asynchronous runtime PM in release fop
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=4bd728a16ee8212e3e468dabb737fe9ef5cea83d;p=openwrt%2Fstaging%2Fblogic.git

[media] exynos4-is: Do not use asynchronous runtime PM in release fop

Use pm_runtime_put_sync() instead of pm_runtime_put() to avoid races
in handling the 'state' bit flags when the fimc-capture drivers'
runtime_resume callback is called from the PM workqueue.
