Subject: [PATCH v2 1/4] scsi: ufs: remove unused min_uA field in struct ufs_vreg
Date: Fri, 15 Mar 2019 17:26:11 +0800	[thread overview]
Message-ID: <1552641974-30672-3-git-send-email-stanley.chu@mediatek.com> (raw)
In-Reply-To: <1552641974-30672-1-git-send-email-stanley.chu-NuS5LvNUpcJWk0Htik3J/w@public.gmane.org>

There are two fields related to regulator current limit in struct
ufs_vreg: "min_uA" and "max_uA".

"max_uA" is probed by "<name>-max-microamp" property from device
tree and used for

- regulator_set_load operations, and
- icc_level configuration in device.

However "min_uA" field is not used anywhere, thus we can remove it.
