From f19234ca8b0af61caf999272862337938a270888 Mon Sep 17 00:00:00 2001 From: Deepak R Varma Date: Mon, 16 Mar 2020 05:12:08 +0530 Subject: [PATCH] staging: fbtft: simplify array index computation An array index is being computed by mathematical calculation on the Lvalue side of the expression. This also further results in the statement exceeding 80 character statement length. A local variable can store the value of the array index computation. The variable can then be used as array index. This improves readability of the code and also address 80 character warning raised by checkpatch.
