[ Upstream commit ee1691d0ae103ba7fd9439800ef454674fadad27 ]
xiic_start_xfer can fail for different reasons:
- EBUSY: bus is busy or i2c messages still in tx_msg or rx_msg
- ETIMEDOUT: timed-out trying to clear the RX fifo
- EINVAL: wrong clock settings
Both EINVAL and ETIMEDOUT will currently print a specific error
message followed by a generic one, for example:
Failed to clear rx fifo
Error xiic_start_xfer
however EBUSY will simply output the generic message:
Error xiic_start_xfer
which is not really helpful.
This commit adds a new error message when a busy condition is detected
and also removes the generic message since it does not provide any
relevant information to the user.

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.
