Breno Leitao d51554dc05 spi: tegra210-quad: Protect curr_xfer clearing in tegra_qspi_non_combined_seq_xfer
[ Upstream commit 6d7723e816 ]

Protect the curr_xfer clearing in tegra_qspi_non_combined_seq_xfer()
with the spinlock to prevent a race with the interrupt handler that
reads this field to check if a transfer is in progress.

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.
