Re: [PATCH 01/13] include: Move ascii85 functions from i915 to linux/ascii85.h

Quoting Jordan Crouse (2018-07-12 19:59:18)

The i915 DRM driver very cleverly used ascii85 encoding for their GPU state file. Move the encode functions to a general header file to support other drivers that might be interested in the same functionality.

v3: Fix error_puts -> err_puts pointed out by the 01.org bot v2: Update API to be cleaner for the caller as suggested by Chris Wilson

+static inline char *

const char * to avoid a compiler warning with return "z".

Looks like that will be ok with the callers.
