Wolfram Sang 1518eb0824 i3c: don't fail if GETHDRCAP is unsupported
[ Upstream commit 447270cdb41b1c8c3621bb14b93a6749f942556e ]

'I3C_BCR_HDR_CAP' is still spec v1.0 and has been renamed to 'advanced
capabilities' in v1.1 onwards. The ST pressure sensor LPS22DF does not
have HDR, but has the 'advanced cap' bit set. The core still wants to
get additional information using the CCC 'GETHDRCAP' (or GETCAPS in v1.1
onwards). Not all controllers support this CCC and will notify the upper
layers about it. For instantiating the device, we can ignore this
unsupported CCC as standard communication will work. Without this patch,
the device will not be instantiated at all.

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.
