No changelog text at all?  I know I don't take patches like that, maybe
other subsystem maintainers are more lax?

Please provide a changelog...

The definition of RFKILL_IOCTL_MAX_SIZE introduced by commit 54f586a91532
is unusable since it is based on RFKILL_IOC_EXT_SIZE which has not been
defined.  Fix that by replacing the undefined constant with the constant
which is intended to be used in this definition.
