Ohad Ben-Cohen 1c8cf9c997 mmc: sdio: fix SDIO suspend/resume regression ... Fix SDIO suspend/resume regression introduced by 4c2ef25fe0 "mmc: fix all hangs related to mmc/sd card insert/removal during suspend/resume": PM: Syncing filesystems ... done. Freezing user space processes ... (elapsed 0.01 seconds) done. Freezing remaining freezable tasks ... (elapsed 0.01 seconds) done. Suspending console(s) (use no_console_suspend to debug) pm_op(): platform_pm_suspend+0x0/0x5c returns -38 PM: Device pxa2xx-mci.0 failed to suspend: error -38 PM: Some devices failed to suspend 4c2ef25fe0 moved the card removal/insertion mechanism out of MMC's suspend/resume path and into pm notifiers (mmc_pm_notify), and that broke SDIO's expectation that mmc_suspend_host() will remove the card, and squash the error, in case -ENOSYS is returned from the bus suspend handler (mmc_sdio_suspend() in this case). mmc_sdio_suspend() is using this whenever at least one of the card's SDIO function drivers does not have suspend/resume handlers - in that case it is agreed to force removal of the entire card. This patch fixes this regression by trivially bringing back that part of mmc_suspend_host(), which was removed by 4c2ef25fe0.
