Common pattern of handling deferred probe can be simplified with dev_err_probe(). Less code and also it prints the error value. Signed-off-by: Krzysztof Kozlowski <krzk@kernel.org> Reviewed-by: Hans de Goede <redacted> --- Changes since v1: 1. Remove unneeded PTR_ERR_OR_ZERO, as pointed by Andy. --- drivers/input/misc/gpio-vibra.c | 20 ++++++-------------- 1 file changed, 6 insertions(+), 14 deletions(-)
