[PATCH 5.15 030/917] media: ir-kbd-i2c: improve responsiveness of hauppauge zilog receivers

From: Greg Kroah-Hartman
Date: Mon Nov 15 2021 - 18:27:46 EST


From: Sean Young <sean@xxxxxxxx>

commit c73ba202a851c0b611ef2c25e568fadeff5e667f upstream.

The IR receiver has two issues:

- Sometimes there is no response to a button press
- Sometimes a button press is repeated when it should not have been

Hanging the polling interval fixes this behaviour.
