Hi!

The issue was caused by only picking up commit 7ab36b51c6bee
("firmware: qcom: scm: request the waitqueue irq *after* initializing
SCM") into stable, while the following four must be applied instead:

23972da96e1ee ("firmware: qcom: scm: remove unused arguments from SHM
bridge routines")
dc3f4e75c54c1 ("firmware: qcom: scm: take struct device as argument in
SHM bridge enable")
87be3e7a2d003 ("firmware: qcom: scm: initialize tzmem before marking
SCM as available")
7ab36b51c6bee ("firmware: qcom: scm: request the waitqueue irq *after*
initializing SCM")
