Subject: [PATCH net v2 0/3] fix xa_alloc_cyclic() return checks
Date: Wed, 12 Mar 2025 10:52:48 +0100	[thread overview]
Message-ID: <20250312095251.2554708-1-michal.swiatkowski@linux.intel.com> (raw)

Pierre Riteau <pierre@stackhpc.com> found suspicious handling an error
from xa_alloc_cyclic() in scheduler code [1]. The same is done in few
other places.

v1 --> v2: [2]
 * add fixes tags
 * fix also the same usage in dpll and phy
