Bus mastering is enabled by firmware, but when this driver is unbinded bus mastering gets disabled by the PCI subsystem which results interrupts not working when driver is reloaded. Hence set bus mastering everytime in probe(). Also - Converted pci_set_dma_mask() and pci_set_consistent_dma_mask() to dma_set_mask_and_coherent(). - Cleared transaction pending bit which gets set during driver unbind due to clearing of bus mastering (ME bit).

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.
