Keep PTR_ERR() calls when the numeric error value is needed for returning the error code. Signed-off-by: Yalagada Pavan Kumar Reviewed-by: Alex Elder --- v5: - Drop arche-apb-ctrl.c and arche-platform.c changes because the files were removed. - keep only the uart.c change, as the fw-core.c changes are already present in staging/staging-next. v4: - Return error codes directly instead of storing them in ret, as suggested by Julia Lawall. - Remove the unused ret variable. v3: - Extend the %pe conversion throughout Greybus, as suggested by Alex Elder. v2: - Use %pe in the firmware management case, as suggested by Jeremy Clifton, to match the other cases. v1: https://lore.kernel.org/outreachy/as0nhVbagZa8Birm@user/T/#t --- drivers/staging/greybus/uart.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/staging/greybus/uart.c b/drivers/staging/greybus/uart.c index d47f00751e7a..74c9898c0eed 100644 --- a/drivers/staging/greybus/uart.c +++ b/drivers/staging/greybus/uart.c @@ -956,7 +956,7 @@ static int gb_tty_init(void) gb_tty_driver = tty_alloc_driver(GB_NUM_MINORS, TTY_DRIVER_REAL_RAW | TTY_DRIVER_DYNAMIC_DEV); if (IS_ERR(gb_tty_driver)) { - pr_err("Can not allocate tty driver\n"); + pr_err("Can not allocate tty driver: %pe\n", gb_tty_driver); retval = PTR_ERR(gb_tty_driver); goto fail_unregister_dev; } -- 2.43.0
