From 4c0a6a0ac902dbf184ae7be1f1fce225cc0b7380 Mon Sep 17 00:00:00 2001 From: Chanwoo Lee Date: Thu, 29 Aug 2024 11:47:09 +0900 Subject: mmc: core: Replace the argument of mmc_sd_switch() with defines Replace with already defined values for readability. While at it, let's also change the mode-parameter from an int to bool, as the only used values are 0 or 1.
