Subject: drivers/rtc: use of_match_ptr() macro
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=c8a6046e1e0bb03406e4fc6c0a204ef58a1868e4;p=linux-beck.git

drivers/rtc: use of_match_ptr() macro

This eliminates having an #ifdef returning NULL for the case when OF is
disabled.  Maintains consistency in cases where OF is always selected.
