From 6e2151c729674aecabf5ec5a96dac97433632009 Mon Sep 17 00:00:00 2001 From: Seung-Woo Kim Date: Mon, 4 Jun 2018 20:45:54 +0900 Subject: [PATCH] fs: fat: fix wrong casting to unsigned value of sect_to_cluster() After the commit 265edc03d5a1 ("fs/fat: Clean up open-coded sector <-> cluster conversions"), it is hung up writing new file to FAT16 disk with more than 19 files in armv7. It is because result value of sect_to_cluster() is not proper by casting from signed value to unsigned value. Fix the wrong casting of sect_to_cluster().
