regulator: core: silence warning: "VDD1: ramp_delay not set"
commit 73e705bf81ce ("regulator: core: Add set_voltage_time op") introduced a new rdev_warn() if the ramp_delay is 0. Apparently, on omap3/twl4030 platforms with dynamic voltage management this results in non-ending spurious messages like [ 511.143066] VDD1: ramp_delay not set [ 511.662322] VDD1: ramp_delay not set [ 513.903625] VDD1: ramp_delay not set [ 514.222198] VDD1: ramp_delay not set [ 517.062835] VDD1: ramp_delay not set [ 517.382568] VDD1: ramp_delay not set [ 520.142791] VDD1: ramp_delay not set [ 520.502593] VDD1: ramp_delay not set [ 523.062896] VDD1: ramp_delay not set [ 523.362701] VDD1: ramp_delay not set [ 526.143035] VDD1: ramp_delay not set I have observed this on GTA04 while it is reported to occur on N900 as well: https://bugzilla.kernel.org/show_bug.cgi?id=178371 This patch makes the warning appear only in debugging mode.
