Subject: Drivers: isdn: hisax: isac.c: Fix assignment and check into one expression.
X-Git-Tag: v4.14-rc1~3496^2~33
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=66391b383b70920629df403f2881ea48805e6659;p=platform%2Fkernel%2Flinux-rpi.git

Drivers: isdn: hisax: isac.c: Fix assignment and check into one expression.

Fix variable assignment inside if statement. It is error-prone and hard to read.
