From 6cac7dc3aaaef8161ac80c5980cec10427996abf Mon Sep 17 00:00:00 2001 From: Rui Miguel Silva Date: Thu, 8 Oct 2015 12:10:52 +0100 Subject: [PATCH] greybus: sdio: fix card removable detection In kernel versions bellow 3.15, the mmc_card_is_removable helper function has an extra check used for a suspend/resume hack. This made the gd_sdio_process_event to behave badly handling the module card insert event in that versions. So, just test bit the flag that we need, instead of using the helper function. This way will work in all kernel versions.
