[PATCH] iio: adc: meson-saradc: check for devm_kasprintf failure

2018-11-21 Thread Nicholas Mc Guire
devm_kasprintf() may return NULL on failure of internal allocation thus the assignments to init.name are not safe if not checked. On error meson_sar_adc_clk_init() returns negative values so -ENOMEM in the (unlikely) failure case of devm_kasprintf() should be fine here. Signed-off-by: Nicholas
