RE: [PATCH] Input: elan_i2c - Reduce the resume time for new dev ices

HI Dmitry: 1. You mean to let all devices ignore skipping reset/sleep part of device initialization? 2. The test team found that some old firmware will have errors (invalid report etc...), so ELAN can only ensure that the new device can meet the newer parts. Thanks jingle -Original Message

HI Dmitry: I would prefer if we validated report length versus the packet type before accepting it. -> If the tracking point report is 0x5F, the report length is 7, but the touchpad report length is 32. -> So, report length will be different with this module. THANKS JINGLE -Or
