fec3a23be0 r6040: fix scheduling while atomic in r6040_tx_timeout
Add a helper function which only modifies R6040 MAC registers
use it when we timeout, and on adapter initialization. Fix
the scheduling while atomic but in the timeout routine due
to the reallocation of rx/tx buffers.

3f6602ad56 drivers/net/r6040.c: Eliminate double sizeof
Taking sizeof the result of sizeof is quite strange and does not seem to be
what is wanted here.

This was fixed using the following semantic patch.

208aefa245 drivers/net/r6040.c: correct bad use of round_jiffies()
Compared to other places in the kernel, I think that this driver misuses
the function round_jiffies.
