Hi Marcel, This patch adds an error recovery mechanism to the btmrvl driver. We have been using it on ChromeOS on kernel v4.19 and it has been on the stable channel release of ChromeOS for a few months now. A side effect of this change is that other functions on the same card will be affected by the reset. The necessary patches to support this reset have already been added to the mwifiex driver by Ulf: 11239229 New [v3,1/3] mwifiex: Re-work support for SDIO HW reset 11239233 New [v3,2/3] mmc: core: Drop check for mmc_card_is_removable() in mmc_rescan() 11239237 New [v3,3/3] mmc: core: Re-work HW reset for SDIO cards You can see more information at crbug.com/1004473 Thanks Abhishek Matthias Kaehlcke (1): Bluetooth: btmrvl: Detect hangs and force a reset of the SDIO card drivers/bluetooth/btmrvl_sdio.c | 24 ++++++++++++++++++++++++ drivers/bluetooth/btmrvl_sdio.h | 1 + 2 files changed, 25 insertions(+) -- 2.25.1.696.g5e7596f4ac-goog
