From: Thierry Reding Date: Wed, 18 Nov 2015 13:04:20 +0000 (+0100) Subject: clk: tegra: Miscellaneous coding style cleanups X-Git-Tag: v4.14-rc1~4001^2~1^2~24 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=e52d7c04bb3911d4ce98bd237f69f5246d9c7083;p=platform%2Fkernel%2Flinux-rpi.git clk: tegra: Miscellaneous coding style cleanups Use unsigned int for loop variables that can never become negative and remove a couple of gratuitous blank lines. Also use single spaces around operators and use a single space instead of a tab to separate comments from code.
