From: Mauro Carvalho Chehab Date: Thu, 16 Jan 2014 14:49:13 +0000 (-0300) Subject: [media] drx-j: Remove a bunch of unused but assigned vars X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=4d7bb0ebbbb00c34fc6f4449d083fe6a55e78db1;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git [media] drx-j: Remove a bunch of unused but assigned vars None of those vars are used on those functions. Just remove them. After this patch, there's just one of such warnings: drivers/media/dvb-frontends/drx39xyj/drxj.c: In function 'ctrl_get_qam_sig_quality': drivers/media/dvb-frontends/drx39xyj/drxj.c:7872:6: warning: variable 'ber_cnt' set but not used [-Wunused-but-set-variable] u32 ber_cnt = 0;
