Hello Rui Miguel Silva,
The patch 3b6ecd6de6b4: "greybus: sdio: extend sdio implementation"
from Jun 22, 2015, leads to the following static checker warning:
drivers/staging/greybus/sdio.c:481 gb_sdio_command()
warn: bitwise AND condition is false here
drivers/staging/greybus/sdio.c
474 ret = gb_operation_sync(host->connection, GB_SDIO_TYPE_COMMAND,
475 &request, sizeof(request), &response,
476 sizeof(response));
477 if (ret < 0)
478 goto out;
479
480 /* no response expected */
481 if (cmd_flags & GB_SDIO_RSP_NONE)
^^^^^^^^^^^^^^^^
This is zero.
482 goto out;
483
regards,
dan carpenter
