From 5b24efe7d55a4bea6992ae1ee00707d77ec22575 Mon Sep 17 00:00:00 2001 From: Sergei Shtylyov Date: Sat, 1 Feb 2020 23:55:08 +0300 Subject: [PATCH] mtd: spi-nor: use le32_to_cpu_array() The driver calls le32_to_cpu() to convert the little-endian tables to a CPU endianness, where le32_to_cpus() should have been called. Was going to use that one... and then discovered a whole array converter, le32_to_cpu_array()! :-) Signed-off-by: Sergei Shtylyov Signed-off-by: Tudor Ambarus --- drivers/mtd/spi-nor/spi-nor.c | 11 ++++------- 1 file changed, 4 insertions(+), 7 deletions(-) diff --git a/drivers/mtd/spi-nor/spi-nor.c b/drivers/mtd/spi-nor/spi-nor.c index 4fc632ec18fe..864ed6f49e87 100644 --- a/drivers/mtd/spi-nor/spi-nor.c +++ b/drivers/mtd/spi-nor/spi-nor.c @@ -3598,8 +3598,7 @@ static int spi_nor_parse_bfpt(struct spi_nor *nor, return err; /* Fix endianness of the BFPT DWORDs. */ - for (i = 0; i < BFPT_DWORD_MAX; i++) - bfpt.dwords[i] = le32_to_cpu(bfpt.dwords[i]); + le32_to_cpu_array(bfpt.dwords, BFPT_DWORD_MAX); /* Number of address bytes. */ switch (bfpt.dwords[BFPT_DWORD(1)] & BFPT_DWORD1_ADDRESS_BYTES_MASK) { @@ -4057,7 +4056,7 @@ static int spi_nor_parse_smpt(struct spi_nor *nor, u32 *smpt; size_t len; u32 addr; - int i, ret; + int ret; /* Read the Sector Map Parameter Table. */ len = smpt_header->length * sizeof(*smpt); @@ -4071,8 +4070,7 @@ static int spi_nor_parse_smpt(struct spi_nor *nor, goto out; /* Fix endianness of the SMPT DWORDs. */ - for (i = 0; i < smpt_header->length; i++) - smpt[i] = le32_to_cpu(smpt[i]); + le32_to_cpu_array(smpt, smpt_header->length); sector_map = spi_nor_get_map_in_use(nor, smpt, smpt_header->length); if (IS_ERR(sector_map)) { @@ -4165,8 +4163,7 @@ static int spi_nor_parse_4bait(struct spi_nor *nor, goto out; /* Fix endianness of the 4BAIT DWORDs. */ - for (i = 0; i < SFDP_4BAIT_DWORD_MAX; i++) - dwords[i] = le32_to_cpu(dwords[i]); + le32_to_cpu_array(dwords, SFDP_4BAIT_DWORD_MAX); /* * Compute the subset of (Fast) Read commands for which the 4-byte -- 2.30.2
