[PATCH] iio: adc: qcom-pm8xxx-xoadc: Remove useless condition in pm8xxx_xoadc_parse_channel()

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

 



The left side of the loop condition never becomes false.
hwchan cannot be NULL, because it points to elements of the
hw_channels array that takes one of 4 predefined values:
pm8018_xoadc_channels, pm8038_xoadc_channels,
pm8058_xoadc_channels, pm8921_xoadc_channels.

Found by Linux Verification Center (linuxtesting.org) with SVACE.

Fixes: 63c3ecd946d4 ("iio: adc: add a driver for Qualcomm PM8xxx HK/XOADC")
