From dbeb101d28eb89a9138055b50d5ce7a9f7a663cf Mon Sep 17 00:00:00 2001 From: Alex Dewar Date: Wed, 28 Oct 2020 15:54:30 +0200 Subject: [PATCH] ath10k: sdio: remove redundant check in for loop The for loop checks whether cur_section is NULL on every iteration, but we know it can never be NULL as there is another check towards the bottom of the loop body. Refactor to avoid this unnecessary check. Also, increment the variable i inline for clarity Addresses-Coverity: 1496984 ("Null pointer dereferences) Suggested-by: Saeed Mahameed Signed-off-by: Alex Dewar Signed-off-by: Kalle Valo Link: https://lore.kernel.org/r/20200916165748.20927-1-alex.dewar90@gmail.com --- drivers/net/wireless/ath/ath10k/sdio.c | 12 +++--------- 1 file changed, 3 insertions(+), 9 deletions(-) diff --git a/drivers/net/wireless/ath/ath10k/sdio.c b/drivers/net/wireless/ath/ath10k/sdio.c index 59043ec44ca37..3e09802cfb6e6 100644 --- a/drivers/net/wireless/ath/ath10k/sdio.c +++ b/drivers/net/wireless/ath/ath10k/sdio.c @@ -2307,8 +2307,8 @@ static int ath10k_sdio_dump_memory_section(struct ath10k *ar, } count = 0; - - for (i = 0; cur_section; i++) { + i = 0; + for (; cur_section; cur_section = next_section) { section_size = cur_section->end - cur_section->start; if (section_size <= 0) { @@ -2318,7 +2318,7 @@ static int ath10k_sdio_dump_memory_section(struct ath10k *ar, break; } - if ((i + 1) == mem_region->section_table.size) { + if (++i == mem_region->section_table.size) { /* last section */ next_section = NULL; skip_size = 0; @@ -2361,12 +2361,6 @@ static int ath10k_sdio_dump_memory_section(struct ath10k *ar, } count += skip_size; - - if (!next_section) - /* this was the last section */ - break; - - cur_section = next_section; } return count; -- 2.30.2
