Subject: [PATCH v1] spi: Respect DataBitLength field of SpiSerialBusV2() ACPI resource
Date: Mon, 13 Apr 2020 21:04:06 +0300	[thread overview]
Message-ID: <20200413180406.1826-1-andriy.shevchenko@linux.intel.com> (raw)

By unknown reason the commit 64bee4d28c9e
  ("spi / ACPI: add ACPI enumeration support")
missed the DataBitLength property to encounter when parse SPI slave
device data from ACPI.

Fill the gap here.

Fixes: 64bee4d28c9e ("spi / ACPI: add ACPI enumeration support")
