From: Axel Lin Date: Fri, 20 Jul 2012 14:22:20 +0000 (+0800) Subject: regulator: lp8788-buck: Remove lp8788_set_default_dvs_ctrl_mode function X-Git-Tag: v3.7-rc1~204^2^5~40 X-Git-Url: https://asedeno.scripts.mit.edu/gitweb/?a=commitdiff_plain;h=c42ea5cdfb14418a9d81e7192d65196b2785c3c2;p=linux.git regulator: lp8788-buck: Remove lp8788_set_default_dvs_ctrl_mode function We already know the mask in lp8788_init_dvs() function, and we can update the corresponding bit for default_dvs_mode in lp8788_init_dvs() function. This function looks not necessary to me.
