Subject: [PATCH] Remove useless FIND_FIRST_BIT() macro from cardbus.c.

  Delete the definition of the unused FIND_FIRST_BIT() macro.

Signed-off-by: Robert P. J. Day <rpjday@...dspring.com>

---

  this macro seems safely deletable, given that there is no other
reference to that macro anywhere in the entire source tree and,
besides, one should use find_first_bit() anyway.

  it's not clear who the official maintainer is for this subsystem
these days.
