Notably, during a resume, the following messages would appear because driver is not able to sync back the cached register values: [1300273.242285] spd5118 2-0050: Failed to write b = 0: -6 [1300273.242297] spd5118 2-0050: PM: dpm_run_callback(): spd5118_resume [spd5118] returns -6 [1300273.242309] spd5118 2-0050: PM: failed to resume async: error -6 [ Fix ] Cherry-pick the following 2 patches: 1. i2c: smbus: introduce Write Disable-aware SPD instantiating functions[1] 2. i2c: i801: Do not instantiate spd5118 under SPD Write Disable[2] [ Tests ] 1. Install and boot the kernel. Check dmesg. The following message should not appear: [ 2.819557] spd5118 2-0050: DDR5 temperature sensor: vendor 0x06:0x32 revision 1.6 2. Suspend the system and resume. The error messages should not appear. [ Where the problem could occur ] This makes the spd5118 device not instantiate at all during the i801 controller probe. This was however what the driver author recommended, so let's do it this way before a better solution appears.
