We observed the failure of initializing card after resume accidentally. It's hard to reproduce but we did get report from the suspend/resume test of our RK3399 mp test farm .Unfortunately, we still fail to figure out what was going wrong at that time. Also we can't achieve it by retrying the host->f_init without falling back it. But this patch will solve the problem as we could add some log there and see that we resume the mmc card successfully after falling back the host->f_init. There is no obviousside effect found, so it seems this patch will improve the stability.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
