[PATCH RFC v2] usb: musb: omap: fix the error check for pm_runtime_get_sync

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

pm_runtime_get_sync returns a signed integer.In case of errors
it returns a negative value.This patch fixes the error check
by making it signed instead of unsigned thus preventing register
access if get_sync_fails. Also passes the error cause to the
debug message.
