Subject: [PATCH AUTOSEL 5.4 066/175] spi: Respect DataBitLength field of SpiSerialBusV2() ACPI resource
Date: Mon,  8 Jun 2020 19:16:59 -0400	[thread overview]
Message-ID: <20200608231848.3366970-66-sashal@kernel.org> (raw)
In-Reply-To: <20200608231848.3366970-1-sashal@kernel.org>

From: Andy Shevchenko <andriy.shevchenko@linux.intel.com>

[ Upstream commit 0dadde344d965566589cd82797893d5aa06557a3 ]

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")
