This patch tries to fix as much as possible of the checkpatch.pl --strict findings: CHECK: Logical continuations should be on the previous line CHECK: No space is necessary after a cast CHECK: Alignment should match open parenthesis CHECK: 'useable' may be misspelled - perhaps 'usable'? WARNING: Possible repeated word: 'is' CHECK: spaces preferred around that '*' (ctx:VxV) CHECK: Comparison to NULL could be written "!msg" CHECK: Prefer kzalloc(sizeof(*zc)...) over kzalloc(sizeof(struct...)...) CHECK: Unnecessary parentheses around resp_type->work CHECK: Avoid CamelCase: <xcRB> There is no functional change comming with this patch, only code cleanup, renaming, whitespaces, indenting, ... but no semantic change in any way. Also the API (zcrypt and pkey header file) is semantically unchanged.
