regulator: lp872x: Remove warning about invalid DVS GPIO
Some devices don't hook the DVS pin to a GPIO but to ground or VCC. In those cases, it is not a problem to have no DVS GPIO provided, as the current code will already switch to software-only DVS selection: When the DVS GPIO is invalid, lp872x_init_dvs jumps to the set_default_dvs_mode label, which instructs the chip not to use the DVS pin at all and do it all in software instead (by clearing the LP8720_EXT_DVS_M bit in the LP872X_GENERAL_CFG register). That is reflected later in the code, when setting the bucks (the DVS pin only applies to the bucks) by checking for the LP8720_EXT_DVS_M bit on the LP872X_GENERAL_CFG register (in lp872x_select_buck_vout_addr) to decide whether to use software or hardware DVS selection. Thus, there is no need to print a warning when the DVS GPIO is invalid. Signed-off-by: Paul Kocialkowski <contact@paulk.fr> Signed-off-by: Mark Brown <broonie@kernel.org>
