[Why] Code reading rxstatus message size was incorrectly assigning it to uint8_t, despite the value being 10 bits long (lower byte plus lowest 2 bits from upper byte). This caused the highest 2 bits to be ignored, potentially missing invalid values. [How] Change all local variables holding rxstatus message size from uint8_t to uint16_t, as in mod_hdcp_message_hdcp2::rx_id_list_size. Replaced untyped HDCP_2_2_HMID_RXSTATUS_MSG_SZ_HI macro with function hdcp_2_2_hmid_rxstatus_msg_sz(const uint8_t[2]) to encapsulate entire calculation and return a typed result. Removed spaces mixed with tabs to fix indentation on modified lines.

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 reStructuredText 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.
