Subject: [PATCH] regulator: lp8788-buck: Remove lp8788_set_default_dvs_ctrl_mode function
Date: Fri, 20 Jul 2012 22:22:20 +0800 [thread overview]
Message-ID: <1342794140.3401.1.camel@phoenix> (raw)
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.
