[patch-2.4.0-test12-pre7] another bugfix for microcode driver

Hi Linus, Unfortunately there was a SMP race between ->read() and ->ioctl() routines (thanks to Mark Hemment for pointing this out!). If one was inside the ->read() after the EOF check and an ioctl requests came in onother CPU which freed the memory and reset the size then one could panic. The
