| H A D | at91_adc.c | c2ab4474 Mon Aug 08 07:42:16 CDT 2016 Anders Darander <anders@chargestorm.se> iio: adc: at91: unbreak channel adc channel 3
The driver always assumes that an input device has been created when
reading channel 3. This causes a kernel panic when dereferencing
st->ts_input.
The change was introduced in
commit 84882b060301 ("iio: adc: at91_adc: Add support for touchscreens
without TSMR"). Earlier versions only entered that part of the if-else
statement if only the following flags are set:
AT91_ADC_IER_XRDY | AT91_ADC_IER_YRDY | AT91_ADC_IER_PRDY
