GCC 12 raises the following warning:

../drivers/net/ice/base/ice_switch.c: In function ‘ice_add_sw_recipe’:
../drivers/net/ice/base/ice_switch.c:7219:61: error: writing 1 byte

      |            ^~~~~~~~~

Since this code is in the base driver, waive the check until the base
driver is fixed by the relevant people.
