Kernel coding style requires more brackets than are strictly required by
C, any block longer than 1 line needs then. Also, if one leg of a
conditional needs them, then they should be on both legs.
Your code has many such instances, please change them all.
This was one issue raised with the OpenSSL review where a lack of
brackets made some coding errors less obvious and in the changes was
down as applying "KNF format the whole source tree"
Probably the easiest fix is to use some tool like "indent --linux-style"
though I am not completely sure that option is perfect.
Certainly if you have code with an odd mix of styles it is much harder
to read, and ultimately source code is for *humans* to understand. So
enforcing a consistent style, even if it is not your own style, makes it
much easier to follow!
Just my 2p worth.

Paul
