[PATCH v2 09/18] iio: afe: iio-rescale: Simplify with dev_err_probe()

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

 



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@xxxxxxxxxx>

Changes since v1:
1. Wrap dev_err_probe() lines at 100 character
