Subject: [PATCH] target: pscsi: avoid Wempty-body warning
Date: Mon, 22 Mar 2021 12:44:34 +0100	[thread overview]
Message-ID: <20210322114441.3479365-1-arnd@kernel.org> (raw)

From: Arnd Bergmann <arnd@arndb.de>

Building with 'make W=1' shows a harmless warning for pscsi:

drivers/target/target_core_pscsi.c: In function 'pscsi_complete_cmd':
drivers/target/target_core_pscsi.c:624:33: error: suggest braces around empty body in an 'if' statement [-Werror=empty-body]
  624 |                                 ; /* XXX: TCM_LOGICAL_UNIT_COMMUNICATION_FAILURE */
      |                                 ^

Rework the coding style as suggested by gcc to avoid the warning.
