The function mse102x_rx_pkt_spi is used in two cases: * initial polling to re-arm RX interrupt * level based RX interrupt handler Both of them doesn't need an open-coded retry mechanism. In the first case the function can be called again, if the return code is IRQ_NONE. This keeps the error behavior during netdev open. In the second case the proper retry would be handled implicit by the SPI interrupt. So drop the retry code and simplify the receive path.

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.
