[ Upstream commit 782a7c73078e1301c0c427f21c06377d77dfa541 ] Commit6a13044849("spi: lpspi: Fix wrong transmission when don't use CONT") breaks transmissions when CONT is used. The TDIE interrupt should not be disabled in all cases. If CONT is used and the TX transfer is not yet completed yet, but the interrupt handler is called because there are characters to be received, TDIE is replaced with FCIE. When the transfer is finally completed, SR_TDF is set but the interrupt handler isn't called again.

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.
