Summary
firmware: arm_scmi: Unwind P2A receiver mailbox setup failure
Details

In the Linux kernel, the following vulnerability has been resolved:

firmware: arm_scmi: Unwind P2A receiver mailbox setup failure

mailbox_chan_setup() can request an additional P2A receiver channel after successfully acquiring the primary P2A channel. If that later request fails, the function returns immediately and leaves the primary channel allocated.

Unwind the primary mailbox channel before returning the error so probe deferral or other setup failures do not leave the channel busy for later probe attempts.
