[PATCH] target: pscsi: avoid Wempty-body warning

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Arnd Bergmann <arnd@xxxxxxxx>

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.
