From 2bfefa4c9632fb09bfe3277cf7b690818b147654 Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Thu, 13 May 2010 22:03:15 +0200 Subject: drivers/mtd: Use kzalloc Use kzalloc rather than the combination of kmalloc and memset. The semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/) // @@ expression x,size,flags; statement S; @@ -x = kmalloc(size,flags); +x = kzalloc(size,flags); if (x == NULL) S -memset(x, 0, size); // Signed-off-by: Julia Lawall Signed-off-by: David Woodhouse --- drivers/mtd/tests/mtd_pagetest.c | 3 +-- drivers/mtd/tests/mtd_readtest.c | 3 +-- drivers/mtd/tests/mtd_speedtest.c | 3 +-- drivers/mtd/tests/mtd_stresstest.c | 3 +-- drivers/mtd/tests/mtd_subpagetest.c | 3 +-- 5 files changed, 5 insertions(+), 10 deletions(-) (limited to 'drivers/mtd/tests') diff --git a/drivers/mtd/tests/mtd_pagetest.c b/drivers/mtd/tests/mtd_pagetest.c index 921a85df9196..6bc1b8276c62 100644 --- a/drivers/mtd/tests/mtd_pagetest.c +++ b/drivers/mtd/tests/mtd_pagetest.c @@ -480,12 +480,11 @@ static int scan_for_bad_eraseblocks(void) { int i, bad = 0; - bbt = kmalloc(ebcnt, GFP_KERNEL); + bbt = kzalloc(ebcnt, GFP_KERNEL); if (!bbt) { printk(PRINT_PREF "error: cannot allocate memory\n"); return -ENOMEM; } - memset(bbt, 0 , ebcnt); printk(PRINT_PREF "scanning for bad eraseblocks\n"); for (i = 0; i < ebcnt; ++i) { diff --git a/drivers/mtd/tests/mtd_readtest.c b/drivers/mtd/tests/mtd_readtest.c index 7107fccbc7de..afe71aa15c4b 100644 --- a/drivers/mtd/tests/mtd_readtest.c +++ b/drivers/mtd/tests/mtd_readtest.c @@ -141,12 +141,11 @@ static int scan_for_bad_eraseblocks(void) { int i, bad = 0; - bbt = kmalloc(ebcnt, GFP_KERNEL); + bbt = kzalloc(ebcnt, GFP_KERNEL); if (!bbt) { printk(PRINT_PREF "error: cannot allocate memory\n"); return -ENOMEM; } - memset(bbt, 0 , ebcnt); /* NOR flash does not implement block_isbad */ if (mtd->block_isbad == NULL) diff --git a/drivers/mtd/tests/mtd_speedtest.c b/drivers/mtd/tests/mtd_speedtest.c index 56ca62bb96bf..161feeb7b8b9 100644 --- a/drivers/mtd/tests/mtd_speedtest.c +++ b/drivers/mtd/tests/mtd_speedtest.c @@ -295,12 +295,11 @@ static int scan_for_bad_eraseblocks(void) { int i, bad = 0; - bbt = kmalloc(ebcnt, GFP_KERNEL); + bbt = kzalloc(ebcnt, GFP_KERNEL); if (!bbt) { printk(PRINT_PREF "error: cannot allocate memory\n"); return -ENOMEM; } - memset(bbt, 0 , ebcnt); /* NOR flash does not implement block_isbad */ if (mtd->block_isbad == NULL) diff --git a/drivers/mtd/tests/mtd_stresstest.c b/drivers/mtd/tests/mtd_stresstest.c index 3854afec56d0..531625fc9259 100644 --- a/drivers/mtd/tests/mtd_stresstest.c +++ b/drivers/mtd/tests/mtd_stresstest.c @@ -221,12 +221,11 @@ static int scan_for_bad_eraseblocks(void) { int i, bad = 0; - bbt = kmalloc(ebcnt, GFP_KERNEL); + bbt = kzalloc(ebcnt, GFP_KERNEL); if (!bbt) { printk(PRINT_PREF "error: cannot allocate memory\n"); return -ENOMEM; } - memset(bbt, 0 , ebcnt); /* NOR flash does not implement block_isbad */ if (mtd->block_isbad == NULL) diff --git a/drivers/mtd/tests/mtd_subpagetest.c b/drivers/mtd/tests/mtd_subpagetest.c index 700237a3d120..11204e8aab5f 100644 --- a/drivers/mtd/tests/mtd_subpagetest.c +++ b/drivers/mtd/tests/mtd_subpagetest.c @@ -354,12 +354,11 @@ static int scan_for_bad_eraseblocks(void) { int i, bad = 0; - bbt = kmalloc(ebcnt, GFP_KERNEL); + bbt = kzalloc(ebcnt, GFP_KERNEL); if (!bbt) { printk(PRINT_PREF "error: cannot allocate memory\n"); return -ENOMEM; } - memset(bbt, 0 , ebcnt); printk(PRINT_PREF "scanning for bad eraseblocks\n"); for (i = 0; i < ebcnt; ++i) { -- cgit v1.2.3
