Subject[PATCH] firmware: stratix10-svc: Fix some error handling paths in 'stratix10_svc_drv_probe()'
Date
If an error occurs after calling 'kfifo_alloc()', the allocated memory
should be freed with 'kfifo_free()', as already done in the remove
function.

Fixes: b5dc75c915cd ("firmware: stratix10-svc: extend svc to support new RSU features")
