[PATCH net-next 4/5] libertas: avoid -Wempty-body warning
From: Arnd Bergmann <arnd@kernel.org>
Date: 2021-03-22 10:46:13
Also in:

Subsystem:
marvell libertas wireless driver, the rest · Maintainer:
Linus Torvalds
From: Arnd Bergmann <arnd@arndb.de>
Building without mesh supports shows a couple of warnings with
'make W=1':
drivers/net/wireless/marvell/libertas/main.c: In function 'lbs_start_card':
drivers/net/wireless/marvell/libertas/main.c:1068:37: error: suggest braces around empty body in an 'if' statement [-Werror=empty-body]
1068 | lbs_start_mesh(priv);
Change the macros to use the usual "do { } while (0)" instead to shut up
the warnings and make the code a litte more robust.
