Subject: staging: rts5208: Rewrite redundant if statement to improve code style
X-Git-Tag: v5.4-rc1~602^2~118
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=34a49d9edf3af971867e3876de7dc9935d467f67;p=platform%2Fkernel%2Flinux-rpi.git

staging: rts5208: Rewrite redundant if statement to improve code style

This commit uses the fact that

    if (a) {
            if (b) {
                    ...
            }
    }

can instead be written as

    if (a && b) {
            ...
    }

without any change in behavior, allowing to decrease the indentation
of the contained code block and thus reducing the average line length.
