Thomas Fourier 568a6afd1d ethernet: atl1: Add missing DMA mapping error checks and count errors
[ Upstream commit d72411d20905180cdc452c553be17481b24463d2 ]

The `dma_map_XXX()` functions can fail and must be checked using
`dma_mapping_error()`.  This patch adds proper error handling for all
DMA mapping calls.

In `atl1_alloc_rx_buffers()`, if DMA mapping fails, the buffer is
deallocated and marked accordingly.

In `atl1_tx_map()`, previously mapped buffers are unmapped and the
packet is dropped on failure.

If `atl1_xmit_frame()` drops the packet, increment the tx_error counter.

Fixes: f3cc28c797 ("Add Attansic L1 ethernet driver.")

README

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.
