Right now, if an error is encountered during the SREV register
read (i.e. an EIO in ath9k_regread()), that error code gets
passed all the way to __ath9k_hw_init(), where it is visible
during the "Chip rev not supported" message.
ath9k_htc 1-1.4:1.0: ath9k_htc: HTC initialized with 33 credits
ath: phy2: Mac Chip Rev 0x0f.3 is not supported by this driver
ath: phy2: Unable to initialize hardware; initialization status: -95
ath: phy2: Unable to initialize hardware; initialization status: -95
ath9k_htc: Failed to initialize the device
Check for -EIO explicitly in ath9k_hw_read_revisions() and return
a boolean based on the success of the operation. Check for that in
__ath9k_hw_init() and abort with a more debugging-friendly message
if reading the revisions wasn't successful.
ath9k_htc 1-1.4:1.0: ath9k_htc: HTC initialized with 33 credits
ath: phy2: Failed to read SREV register
ath: phy2: Could not read hardware revision
ath: phy2: Unable to initialize hardware; initialization status: -95
ath: phy2: Unable to initialize hardware; initialization status: -95
ath9k_htc: Failed to initialize the device
This helps when debugging by directly showing the first point of
failure and it could prevent possible errors if a 0x0f.3 revision
is ever supported.

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.
