[PATCH v9 2/3] pinctrl: qcom: do not reinitialize gpio valid mask

From: Richard Acayan
Date: Fri Oct 07 2022 - 17:33:03 EST


It may be necessary for some devices to specify reserved gpios in the
device-specific DTS, in addition to the reserved gpios common to all
devices with a given SoC. Remove this bitmap_fill() call so that the
settings applied to the gpio valid mask by DTS are not overridden by
the driver's reserved gpios.
