Subject: [PATCH] EDAC: Use kcalloc()
Date: Tue, 12 Apr 2022 23:19:57 +0200 [thread overview]
Message-ID: <20220412211957.28899-1-bp@alien8.de> (raw)
From: Borislav Petkov <bp@suse.de>
It is syntactic sugar anyway:
# drivers/edac/edac_mc.o:
text data bss dec hex filename
13378 324 8 13710 358e edac_mc.o.before
13378 324 8 13710 358e edac_mc.o.after
md5:
70a53ee3ac7f867730e35c2be9110748 edac_mc.o.before.asm
70a53ee3ac7f867730e35c2be9110748 edac_mc.o.after.asm
# drivers/edac/edac_device.o:
text data bss dec hex filename
5684 120 4 5808 16b0 edac_device.o.before
5684 120 4 5808 16b0 edac_device.o.after
md5:
811325c80acb5a1d6df7b290df3e1636 edac_device.o.before.asm
811325c80acb5a1d6df7b290df3e1636 edac_device.o.after.asm
No functional changes.
