Subject: [PATCH 1134/1135] drivers: mmc: core: handle card-removal when
|
||
|
|
running CQE recovery
|
||
|
|
|
||
|
|
Recovery claims the MMC card so the card-detect work gets significantly
|
||
|
|
delayed - leading to lots of error recovery loops that can never do
|
||
|
|
anything but fail.
|
||
|
|
|
||
|
|
Explicitly detect the card after CQE has halted and bail if it's not
|
||
|
|
there.
|
||
|
|
|
||
|
|
Also ratelimit a not-very-descriptive warning - one occurrence in dmesg
|
||
|
|
is enough to signal that something is amiss.
