Commit 273b902a5b1bfd6977a73c4de3eb96db3cb103cb removed inversion in
features check conditionals (by accident, perhaps). That change resulted
in erroneous reporting that device can't receive while actually it can.
Fix this.

Hi Alexey,
this has been already fixed in commit bd291208d7f5 ("[media]
lirc_dev: LIRC_{G,S}ET_REC_MODE do not work") by Sean.
You need to update your kernel or cherry-pick this patch.
In any case, for future patches of this kind, some notes through
the lines:
