| Subject: watchdog: keembay: Removed timeout update in the TO ISR |
| |
| From: Shruthi Sanil <shruthi.sanil@intel.com> |
| |
| [ Upstream commit 3168be5d66ac6c3508a880022f79b5a887865d5d ] |
| |
| In the TO ISR removed updating the Timeout value because |
| its not serving any purpose as the timer would have already expired |
| and the system would be rebooting. |
