[ Upstream commit 1a394b3c3de2577f200cb623c52a5c2b82805cec ]
link_rate is updated via debugfs using hex values, set it to output in hex as well.
eg: Resolution: 1920x1080@144Hz cat /sys/kernel/debug/dri/0/DP-1/link_settings Current: 4 0x14 0 Verified: 4 0x1e 0 Reported: 4 0x1e 16 Preferred: 0 0x0 0
echo "4 0x1e" > /sys/kernel/debug/dri/0/DP-1/link_settings
cat /sys/kernel/debug/dri/0/DP-1/link_settings Current: 4 0x1e 0 Verified: 4 0x1e 0 Reported: 4 0x1e 16 Preferred: 4 0x1e 0
