From 29e3e06d893105febb9c9ccaff856fcdcbe3f712 Mon Sep 17 00:00:00 2001 From: Phil Reid Date: Mon, 27 Jun 2016 11:17:56 +0800 Subject: [PATCH] iio: buffer-dma: Use ARRAY_SIZE in for loop range Use the ARRAY_SIZE macro in the for loops that access queue->fileio.blocks. Macro is already used in a couple of places where this access occurs, but range was hardcoded in these locations.
