Subject: [PATCH] firmware: microchip: Fix over-requested allocation size
Date: Mon, 4 Mar 2024 17:25:32 +0800 [thread overview]
Message-ID: <20240304092532.125751-1-dawei.li@shingroup.cn> (raw)
cocci warnings: (new ones prefixed by >>)
>> drivers/firmware/microchip/mpfs-auto-update.c:387:72-78:
ERROR: application of sizeof to pointer
drivers/firmware/microchip/mpfs-auto-update.c:170:72-78:
ERROR: application of sizeof to pointer
response_msg is a pointer to u32, so the size of element it points to is
supposed to be a multiple of sizeof(u32), rather than sizeof(u32 *).
