Subject: [PATCH] power: supply: sbs-manager: normalize return value of gpio_get
Date: Wed, 18 Feb 2026 12:59:49 -0800	[thread overview]
Message-ID: <aZYoL2MnTYU5FuQh@google.com> (raw)

The GPIO get callback is expected to return 0 or 1 (or a negative error
code). Ensure that the value returned by sbsm_gpio_get_value() is
normalized to the [0, 1] range.
