mmc_sd_num_wr_blocks() has an interesting construction that saves one return argument by casting (u32)-1 as error code if something goes wrong. This is however a bit confusing when the normal kernel pattern is to return an int error code on success. So instead pass a variable "blocks" that the function can fill in with the number of successfully transferred blocks and return an integer as error code.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. 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.
