Subject: rtc: fix module reference count in rtc-proc
X-Git-Tag: v4.14-rc1~3987^2~22
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=b01079be449b895913ce17a47933820af708d5dd;p=platform%2Fkernel%2Flinux-rpi.git

rtc: fix module reference count in rtc-proc

rtc-proc.c is not built as a module. Thus, rather than dealing with
THIS_MODULE's reference count, we should deal with rtc->owner's
reference count.
