The snd_pcm name may overflow the card->longname total size:
sound/isa/cs423x/cs4231.c: In function 'snd_cs4231_probe':
sound/isa/cs423x/cs4231.c:115:26: error: ' at 0x' directive writing 6 bytes into a region of size between 1 and 80 [-Werror=format-overflow=] 0x%lx, irq %d, dma %d",
sprintf(card->longname, "%s at 0x%lx, irq %d, dma %d",
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~
This changes the driver to use snprintf() so we truncate the string
instead of overflowing into the next field if that happens.
I decided to split out the second format string for the extra
DMA channel to keep the code simpler.

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.
