From 5bda642bcb0fc6004f08d8acdfe0e71d5b3c5012 Mon Sep 17 00:00:00 2001 From: Furquan Shaikh Date: Fri, 7 Apr 2017 07:13:24 -0700 Subject: drivers/spi: Get rid of spi_get_config There is only one user for spi_get_config i.e. SPI ACPI. Also, the values provided by spi_get_config are constant for now. Thus, get rid of the spi_get_config call and fill in these constant values in SPI ACPI code itself. If there is a need in the future to change these, appropriate device-tree configs can be added.
