Subject: rt2x00: Increase REGISTER_BUSY_COUNT
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=ae4ecb9f8f01eb9deffb5bd837dc90f4e646cd2d;p=deliverable%2Flinux.git

rt2x00: Increase REGISTER_BUSY_COUNT

For some hardware the REGISTER_BUSY_COUNT isn't sufficient,
increase the REGISTER_BUSY_COUNT to 100 to catch most
devices which have more problems with accessing the registers.

For normal operating devices nothing would change as they will
exit the loop early anyway.
