Subject: ASoC: tfa9879: Fix return value check in tfa9879_i2c_probe()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=427ced4b203dfea4f08b1298cd1f88e19039fca4;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

ASoC: tfa9879: Fix return value check in tfa9879_i2c_probe()

In case of error, the function devm_kzalloc() returns NULL
not ERR_PTR(). The IS_ERR() test in the return value check
should be replaced with NULL test.
