Instead of open-coding this each time, perhaps it would be appropriate
to define a macro to possibly put a character and also advance the
pointer.
Assuming that the locals are consistently "out" and "end", something
like
#define addch(c) do { \
if(out < end) *out = c; \
++out; \
} while(0)
modulo any errors or differences with standard kernel coding style.
