Subject: [PATCH] checkpatch: update seq_<foo> tests
seq_vprintf, seq_printf and seq_puts are logging functions and should be
allowed to exceed the maximium line length.
Add maximum line length exceptions for these functions.
Also, suggesting seq_printf conversions to seq_puts should be tested for
arguments after the format.
