Subject: [PATCH net-next] eth: ice: silence the GCC 12 array-bounds warning
Date: Thu, 19 May 2022 23:09:06 -0700 [thread overview]
Message-ID: <20220520060906.2311308-1-kuba@kernel.org> (raw)
GCC 12 gets upset because driver allocates partial
struct ice_aqc_sw_rules_elem buffers. The writes are
within bounds.
Silence these warnings for now, our build bot runs GCC 12
so we won't allow any new instances.
