Subject: drivers/rtc/rtc-tps65910.c: fix incorrect return value on error
X-Git-Tag: upstream/snapshot3+hdmi~5276^2~93
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=dbda161be8ae43133bbeac34da3ad99ffeb63556;p=platform%2Fadaptation%2Frenesas_rcar%2Frenesas_kernel.git

drivers/rtc/rtc-tps65910.c: fix incorrect return value on error

'ret' was not initialized to correct error value before returning.
Since 'irq' is also being tested for 0, we cannot return irq itself as
it means function is success even though we are returning before
completing the probe.
