If the requested firmware file size is 0 bytes in the filesytem, we will try to vmalloc(0), which causes a warning: vmalloc: allocation failure: 0 bytes kworker/1:1: page allocation failure: order:0, mode:0xd2 __vmalloc_node_range+0x164/0x208 __vmalloc_node+0x4c/0x58 vmalloc+0x38/0x44 _request_firmware_load+0x220/0x6b0 request_firmware+0x64/0xc8 wl18xx_setup+0xb4/0x570 [wl18xx] wlcore_nvs_cb+0x64/0x9f8 [wlcore] request_firmware_work_func+0x94/0x100 process_one_work+0x1d0/0x750 worker_thread+0x184/0x4ac kthread+0xb4/0xc0 To fix this, check whether the file size is less than or equal to zero in fw_read_file_contents().
