Input: silead - disable interrupt during suspend
When we put the touchscreen controller in low-power mode the irq pin may trigger (float) and if we then try to read a data packet we get the following error in dmesg: [ 478.801017] silead_ts i2c-MSSL1680:00: Data read error -121 This commit disables the irq during suspend/resume fixing this error.
