Subject: eth: ice: silence the GCC 12 array-bounds warning
X-Git-Tag: v5.19-rc1~159^2~15^2~1
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=385bc51b41ea74a91545600cb3d731754372f75e;p=thirdparty%2Fkernel%2Flinux.git

eth: ice: silence the GCC 12 array-bounds warning

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.
