Build test (gcc version 11.3.1 20220819):
mips: 62 configs -> no failure
arm: 99 configs -> no failure
arm64: 3 configs -> no failure
x86_64: 4 configs -> no failure
alpha allmodconfig -> no failure
csky allmodconfig -> no failure
powerpc allmodconfig -> no failure
riscv allmodconfig -> no failure
s390 allmodconfig -> no failure
xtensa allmodconfig -> no failure

Note:
x86_64 allmodconfig failed with gcc-12 with the error:

drivers/net/wwan/iosm/iosm_ipc_protocol_ops.c: In function 'ipc_protocol_dl_td_process':
drivers/net/wwan/iosm/iosm_ipc_protocol_ops.c:406:13: error: the comparison will always evaluate as 'true' for the address of 'cb' will never be NULL [-Werror=address]

It will need dbbc7d04c549 ("net: wwan: iosm: remove pointless null check").

Boot test:
x86_64: Booted on my test laptop. No regression.
x86_64: Booted on qemu. No regression. [1]
arm64: Booted on rpi4b (4GB model). No regression. [2]
mips: Booted on ci20 board. No regression. [3]
