Subject: watchdog: use dev_get_platdata()
X-Git-Tag: upstream/snapshot3+hdmi~3931^2~22
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=bc8fdfbe75058c6569dd6a08bdc2a411db533c47;p=platform%2Fadaptation%2Frenesas_rcar%2Frenesas_kernel.git

watchdog: use dev_get_platdata()

Use the wrapper function for retrieving the platform data instead of
accessing dev->platform_data directly.
