Shuah Khan c1c98764c3 misc: rtsx_usb: set return value in rsp_buf alloc err path 
commit 2cd37c2e72 upstream.

Set return value in rsp_buf alloc error path before going to
error handling.

drivers/misc/cardreader/rtsx_usb.c:639:6: warning: variable 'ret' is used uninitialized whenever 'if' condition is true [-Wsometimes-uninitialized]
           if (!ucr->rsp_buf)
               ^~~~~~~~~~~~~
   drivers/misc/cardreader/rtsx_usb.c:678:9: note: uninitialized use occurs here
           return ret;
                  ^~~
   drivers/misc/cardreader/rtsx_usb.c:639:2: note: remove the 'if' if its condition is always false
           if (!ucr->rsp_buf)
           ^~~~~~~~~~~~~~~~~~
   drivers/misc/cardreader/rtsx_usb.c:622:9: note: initialize the variable 'ret' to silence this warning
           int ret;
                  ^
                   = 0

README 

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.
