[PATCH] usb: Use readl while handling PCI quirks

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

 



From: Jayachandran C <jayachandranc@xxxxxxxxxxxxxxxxx>

The USB driver code usually uses readl() to read the EHCI register
space to support chips which does not allow 8/16 bit access to the
EHCI registers.

But in the PCI USB quirk code (drivers/usb/host/pci-quirks.c),
readb() is used in one place. Convert this to use readl as well.

[ The Netlogic XLP patches I plan to submit is dependent on this, 
 otherwise we will need to fix this up with a custom Cache error
 handler. Let me know if this is not the right approach. - Thanks.]
