Receiving the first packet in an AMS sequence signals the beginning of AMS. Set in_ams flag to true when SRC_CAPS are received during POWER_NEGOTIATION AMS. This fixes the failure flagged while running TD.PD.SNK.E9 compliance test. >From Deterministic PD compliance MOI spec: TD.PD.SNK.E9. GetSinkCap in Place of Accept Description: As Provider, the Tester intentionally sends a GetSinkCap message in place of Accept message and verifies the UUT will send a SoftReset and recover from the error. Steps: a) Run PROC.PD.E1 Bring-up according to the UUT role. b) The Tester cycles VBus. c) The Tester sends a Source Capabilities message to the UUT. d) Upon receipt of a Request message from the UUT, the Tester replies with a GoodCRC message. e) The Tester sends a GetSinkCap message to the UUT. f) If a SoftReset is not received within 15 ms after the GetSinkCap EOP was sent, the test fails. g) If a SoftReset is received timely, the Tester replies with an Accept message. h) The Tester sends Source Capabilities message to the UUT repeatedly until nCapsCount reached or a GoodCRC is received. If nCapsCount reached, the test fails. i) If a Request is not received timely within 30 ms after the GoodCRC EOP corresponding to Source Capabilities message was received, the test fails.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
