It'd be fine with me, but maybe others will object.

I think it's okay to indent new C code with spaces, but when a few
lines are modified in an otherwise TAB-indented block, that makes the
source unaligned when reindented, so IMO should be avoided.  And in
this case, it was even more extreme: a line was modified only very
slightly, so changing whitespace for only that single line was IMO
gross.
