Subject: [PATCH 2/4] iio: magnetometer: ak8975: replace usleep_range() with fsleep()
Date: Mon, 20 Apr 2026 11:08:02 +0000 [thread overview]
Message-ID: <20260420110804.1353-3-joshua.crofts1@gmail.com> (raw)
In-Reply-To: <20260420110804.1353-1-joshua.crofts1@gmail.com>
Replace usleep_range() calls with fsleep(), passing the minimum value
required by the sensor for hardware delays.
fsleep() automatically selects the optimal sleep mechanism, simplifying
driver code and time management.
