From: Andy Shevchenko <andriy.shevchenko@xxxxxxxxxxxxxxx> [ 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.
