From 2ff5e1532dd37e1bd8ac72da3f7f0e2b310102fb Mon Sep 17 00:00:00 2001 From: Xi Wang Date: Mon, 9 Jan 2012 16:58:25 -0500 Subject: [PATCH] mtd: pmc551: fix signedness bug in init_pmc551() Since "length" is a u32, the error handling below didn't work when fixup_pmc551() returns -ENODEV. if ((length = fixup_pmc551(PCI_Device)) <= 0) This patch changes both the type of "length" and the return type of fixup_pmc551() to int.
