After the first check of the value of the "eft" variable
it does not change, it is obvious that a copy-paste
error was made here and the value of variable "alm"
should be checked here.
Found by Linux Verification Center (linuxtesting.org) with SVACE.
Fixes: 101ca8d05913 ("rtc: efi: Enable SET/GET WAKEUP services as optional")

I had a look at the history and this is actually a bug that predates
v2.6.12-rc2 and so its introduction is not in the main git repo history.
I guess nobody actually cares and I'm very tempted to just rip out this
procfs file.
