Greg Kroah-Hartman 47446b50ad firmware_loader: fix up to_fw_sysfs() to preserve const ...

to_fw_sysfs() was changed in commit 23680f0b7d ("driver core: make
struct class.dev_uevent() take a const *") to pass in a const pointer
but not pass it back out to handle some changes in the driver core.
That isn't the best idea as it could cause problems if used incorrectly,
so switch to use the container_of_const() macro instead which will
preserve the const status of the pointer and enforce it by the compiler.
