Subject: [PATCH v1 1/1] spi: Replace custom fsleep() implementation
Date: Wed, 5 Feb 2025 15:06:24 +0200 [thread overview]
Message-ID: <20250205130624.716039-1-andriy.shevchenko@linux.intel.com> (raw)
_spi_transfer_delay_ns() partially reimplements what fsleep() does.
Replace that code by calling fsleep() instead.
