Subject: [PATCH] regulator: helper: Document ramp_delay parameter of regulator_set_ramp_delay_regmap()

From: ChiYuan Huang <cy_huang@...htek.com>

With W=1:

    drivers/regulator/helpers.c:947: warning: Function parameter or member 'ramp_delay' not described in 'regulator_set_ramp_delay_regmap'

Fix it by documenting the parameter.

Fixes: fb8fee9efdcf ("regulator: Add regmap helper for ramp-delay setting")
