[patch 14/17] scsi: fix bad use of udelay in atp870u.c

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Martin Michlmayr <tbm@xxxxxxxxxx>

The ACARD driver calls udelay() with a value > 2000, which leads to
to the following compilation error on ARM:
  ERROR: "__bad_udelay" [drivers/scsi/atp870u.ko] undefined!
  make[1]: *** [__modpost] Error 1
Fix this by using a combination of mdelay and udelay.
