Subject: i2c: omap: on ->remove() call pm_runtime_put_sync()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=1c4828f916ffd5b7cc4d57d832cce615475b36da;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

i2c: omap: on ->remove() call pm_runtime_put_sync()

we're about to remove the module, so we can't
really schedule a PM transition in the future,
we must wait for it to finish.
