6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Balaji Pothunoori <quic_bpothuno@xxxxxxxxxxx>
commit 8a47704d64c9afda80e7f399ba2cf898cfcc45b2 upstream.
Currently, the rproc "atomic_t power" variable is incremented during:
a. WPSS rproc auto boot.
b. AHB power on for ath11k.
During AHB power off (rmmod ath11k_ahb.ko), rproc_shutdown fails
to unload the WPSS firmware because the rproc->power value is '2',
causing the atomic_dec_and_test(&rproc->power) condition to fail.
Consequently, during AHB power on (insmod ath11k_ahb.ko),
QMI_WLANFW_HOST_CAP_REQ_V01 fails due to the host and firmware QMI
states being out of sync.
