Could I get some comment on this grouping for types:
Allocation Style: ALLOC_ARRAY_ARGS, ALLOC_SIZEOF_STRUCT, ALLOC_WITH_MULTIPLY
API Usage: ARCH_DEFINES, ARCH_INCLUDE_LINUX, ARRAY_SIZE, AVOID_BUG,
AVOID_EXTERNS, AVOID_L_PREFIX, BIT_MACRO, CONSIDER_KSTRTO
Comment Style: BLOCK_COMMENT_STYLE, C99_COMMENTS
Commit Message: BAD_SIGN_OFF, BAD_STABLE_ADDRESS_STYLE, COMMIT_COMMENT_SYMBOL,
Comparison Style: ASSIGN_IN_IF, BOOL_COMPARISON, COMPARISON_TO_NULL,
Spacing & Brackets: ASSIGNMENT_CONTINUATIONS, BRACES, BRACKET_SPACE,
Others: CAMELCASE, CONFIG_DESCRIPTION
This is what I have done till now. Any suggestions would be nice and if it looks
okay I would like to send the v4 in.
Thanks & Regards,
