Public bug reported:
SRU Justification
[Impact]
When CQE is disabled, the eMMC driver generates a warning at
mmc_mq_queue_rq. This is due to pending_writes underflowing, introduced
by a double-decrement in commit e6c1e86.
[Fix]
Pull the fix from upstream Raspberry Pi tree (rpi-6.18.y branch):
- eacf886641f74 mmc: block: Fix pending_writes underflow on non-CQE hosts
[Test Plan]
* Compile tested
* Boot tested
* No impacts to existing features found
Install the built packages, reboot the machine and the warning should
disappear from kernel logs.
[Regression potential]
Relatively low, as change is a bug fix from upstream.
