From: David Lechner Date: Wed, 7 May 2025 20:42:43 +0000 (-0500) Subject: iio: adc: ad4695: rename AD4695_MAX_VIN_CHANNELS X-Git-Url: http://git.monstr.eu/?a=commitdiff_plain;h=76a67e394d11e63d427dde89831166f29c335d68;p=linux-2.6-microblaze.git iio: adc: ad4695: rename AD4695_MAX_VIN_CHANNELS Rename AD4695_MAX_CHANNELS to AD4695_MAX_VIN_CHANNELS. It has been a point of confusion that this macro is only the voltage input channels and not all channels.
