[PATCH v2 02/11] firmware: arm_ffa: Skip free_pages on RX buffer alloc failure

[Sudeep Holla <sudeep.holla@kernel.org>]

If the RX buffer allocation fails in ffa_init(), the error path jumps to
free_pages even though no buffer has been allocated yet. Route that case
directly to free_drv_info so the cleanup path is only used after at
least one RX/TX buffer allocation has succeeded.

Fixes: 3bbfe9871005 ("firmware: arm_ffa: Add initial Arm FFA driver support")
