From 90e5154c737cf1c5fca53ce47354346e13df8942 Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Mon, 13 Apr 2020 21:04:06 +0300 Subject: [PATCH] spi: Respect DataBitLength field of SpiSerialBusV2() ACPI resource [ 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.
