From 9c5b19c2eea8cb8d5784dedce8cac07e9a20198e Mon Sep 17 00:00:00 2001 From: Yang Li Date: Mon, 26 Apr 2021 17:32:23 +0800 Subject: [PATCH] mtd: *nftl: return -ENOMEM when kmalloc failed The driver is using -1 instead of the -ENOMEM defined macro to specify that a buffer allocation failed. Using the correct error code is more intuitive Smatch tool warning: drivers/mtd/inftlmount.c:333 check_free_sectors() warn: returning -1 instead of -ENOMEM is sloppy drivers/mtd/nftlmount.c:272 check_free_sectors() warn: returning -1 instead of -ENOMEM is sloppy No functional change, just more standardized.
