From 871a4073f438c61cc4cf7471476d9a8a29ccf620 Mon Sep 17 00:00:00 2001 From: Boris Brezillon Date: Sat, 4 Aug 2018 22:59:22 +0200 Subject: [PATCH] mtd: rawnand: Make maxchips an unsigned int There's no good reason to make maxchips a signed integer, since only positive values are valid. Make it an unsigned int.
