Subject: [PATCH 1/6] iio: adc: max11100: Constify struct iio_chan_spec
Date: Tue, 26 May 2020 23:02:18 +0200 [thread overview]
Message-ID: <20200526210223.1672-2-rikard.falkeborn@gmail.com> (raw)
In-Reply-To: <20200526210223.1672-1-rikard.falkeborn@gmail.com>
max11100_channels is not modified and can therefore be made const to
allow the compiler to put it in read-only memory.
Before:
text data bss dec hex filename
3776 1168 0 4944 1350 drivers/iio/adc/max11100.o
After:
