Subject: serial: omap: fix sequence of pm_runtime_* calls.
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=856e35bf596e83a63c8a9ec749e9f2bcd24a1bdd;p=linux-beck.git

serial: omap: fix sequence of pm_runtime_* calls.

pm_runtime_enable() needs to be invoked before
pm_runtime_use_autosuspend(), and
pm_runtime_set_autosuspend_delay() functions.
