Zhengchao ShaoandGreg Kroah-Hartman 0b5a89e8bc test_firmware: fix memory leak in test_firmware_init() 
[ Upstream commit 7610615e8c ]

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):
  comm "insmod", pid 7952, jiffies 4294948236 (age 49.060s)
  hex dump (first 32 bytes):
    74 65 73 74 2d 66 69 72 6d 77 61 72 65 2e 62 69  test-firmware.bi
    6e 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00  n...............
