Subject: [media] omap3isp: resizer: Remove needless variable initializations
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=41316a27ee96b31970175bec87210075752001fb;p=linux-beck.git

[media] omap3isp: resizer: Remove needless variable initializations

There's no need to initialize local variables to zero when they're
explicitly assigned another value right after. Remove the needless
initializations.
