The module probing logic there is a way more complex than it should be, and requires some special magic to avoid stack overflows when KASAN is enabled. Solve it by creating ancillary functions to setup the platform data and request module. Now, the probing functions are cleaner and easier to understand. As a side effect, the size of the module was reduced by about 9.7% on x86_64: Before this patch: text data bss dec hex filename 51090 14192 96 65378 ff62 drivers/media/usb/em28xx/em28xx-dvb.o After this patch: text data bss dec hex filename 44743 14192 96 59031 e697 drivers/media/usb/em28xx/em28xx-dvb.o Tested with a PCTV 461e device.

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.
