struct rzt2h_adc::max_channels is unused, and is probably a leftover of the devm_iio_adc_device_alloc_chaninfo_se() conversion done after the initial submission. Remove it and the logic used to set it. Signed-off-by: Cosmin Tanislav <cosmin-gabriel.tanislav.xa@renesas.com> --- drivers/iio/adc/rzt2h_adc.c | 6 ------ 1 file changed, 6 deletions(-)
