Commit Message

Zhang Qilong June 2, 2022, 3:13 a.m. UTC 
a) Add missing pm_runtime_disable() when probe error out. It could
avoid pm_runtime implementation complains when removing and probing
again the driver.
b) Add remove for missing pm_runtime_disable().

v2:
--- Add remove to put PM usage counter.

v3:
--- Modify commit message.
