Subject: checkpatch: allow multiple const * types
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=1574a29f8e769998fe3e55eb6030dc61e3d09ccd;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

checkpatch: allow multiple const * types

checkpatch's $Type variable does not match declarations of multiple
const * types.

This can produce false positives for things like:

  $ ./scripts/checkpatch.pl -f drivers/staging/comedi/comedidev.h
  WARNING: Missing a blank line after declarations
  #60: FILE: drivers/staging/comedi/comedidev.h:60:
  +       const struct comedi_lrange *range_table;
  +       const struct comedi_lrange *const *range_table_list;

Fix the $Type variable to support matching multiple "* const" uses.
