checkpatch: add support for floating point constants
Even though the kernel doesn't support using floating point constants, add a regex for them. Support forms like: 0x123p1, 123e-1, 1.23, 1.5e23f Signed-off-by: Joe Perches <joe@perches.com> Cc: Andy Whitcroft <apw@canonical.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
