[PATCH -next] firmware: arm_scmi: optee: Fix missing mutex_init()
From: Wei Yongjun <hidden>

Subsystem:
system control & power/management interface (scpi/scmi) message protocol drivers, the rest · Maintainers:

The driver allocates the mutex but not initialize it.
Use mutex_init() on it to initialize it correctly.
