[SRU][J/N:linux-bluefield][PATCH v1 0/1] platform/mellanox: mlxbf-pka: fix the PKA shim mutex initialization issue

[Ron Li]

BugLink: https://bugs.launchpad.net/bugs/2127200

SRU Justification:

[Impact]

In the existing PKA driver implementation, in function pka_dev_init_shim, the shim->mutex is first used in the pka_dev_trng_read function. However, the mutex is initialized after the pka_dev_trng_read function. This causes runtime kernel lock warning.

[Fix]

* Move the mutex initialization before the TRNG related function calls.

[Test Case]

* Verify the PKA devices can be successfully probed during kernel boot.

[Other]
* This code is likely to change depending on feedback we received from maintainers.
