Subject: [PATCH v2 0/2] meson-mx-sdhc card busy detection fixes
Date: Thu, 16 Apr 2020 20:35:11 +0200	[thread overview]
Message-ID: <20200416183513.993763-1-martin.blumenstingl@googlemail.com> (raw)

The following errors were observed with Linux 5.7-rc1 and an SD card
hooked up to the meson-mx-sdio controller:
  mmc1: Card stuck being busy! __mmc_poll_for_busy
  blk_update_request: I/O error, dev mmcblk1, sector 17111080 op
   0x3:(DISCARD) flags 0x0 phys_seg 1 prio class 0

At least patch #1 should go to a -fixes branch so it can make it
into v5.7.

Changes since v1 at [0]:
- added correct Fixes tag for patch #1
- added a patch which drops the ->card_busy() implementation from
  the meson-mx-sdio driver because this is not working
- special thanks to Ulf for taking the time to provide debug
  patches, explaining things and answering my questions!
