Description
In the Linux kernel, the following vulnerability has been resolved:
test_firmware: fix memory leak in test_firmware_init()
When misc_register() failed in test_firmware_init(), the memory pointed
by test_fw_config->name is not released. The memory leak information is
as follows:
unreferenced object 0xffff88810a34cb00 (size 32):
