Subject: [PATCH 14/17] lirc: make chardev nonseekable
Merge change from upstream kernel
commit d9d2e9d5c9eead1f73f92f5fc03424dab90b6c95
Author: Arnd Bergmann <arnd@arndb.de>

lirc: make chardev nonseekable
There does not seem to be a need for lirc to
allow seeking on the file descriptor, so let's
just disallow this before users start relying
on it.
