In the case of ((max9877_regs[reg] >> shift) & mask) != val
but ((max9877_regs[reg2] >> shift) & mask) == val2,
current code does not update the registers.
Fix the logic to update registers if either val or val2 is changed.

According to the datasheet:
The BIT[5:4] of ADC Control Register 2 is to control the word width.
00 = 25 Bits
01 = 20 Bits
10 = 16 Bits
11 = Invalid
Thus, the AD1836_ADC_WORD_OFFSET should be defined as 4.

.. with new name. Because nothing says "really solid kernel release"
like naming it after an extinct animal that just happened to be in the
news lately.
Mountpoint crossing is similar to following procfs symlinks - we do
not get ->d_revalidate() called for dentry we have arrived at, with
unpleasant consequences for NFS4.
Simple way to reproduce the problem in mainline:
cat >/tmp/a.c <<'EOF'
#include <unistd.h>
#include <fcntl.h>
#include <stdio.h>
main()
{
struct flock fl = {.l_type = F_RDLCK, .l_whence = SEEK_SET, .l_len = 1};
if (fcntl(0, F_SETLK, &fl))
perror("setlk");
}
EOF
cc /tmp/a.c -o /tmp/test
then on nfs4:
mount --bind file1 file2
/tmp/test < file1 # ok
/tmp/test < file2 # spews "setlk: No locks available"...
What happens is the missing call of ->d_revalidate() after mountpoint
crossing and that's where NFS4 would issue OPEN request to server.
The fix is simple - treat mountpoint crossing the same way we deal with
following procfs-style symlinks. I.e. set LOOKUP_JUMPED...

Rx byte count was off; instead use the hardware's count. Tx packet
count was counting pre-TSO packets; instead count on-the-wire packets.
Report hardware dropped frame count as rx_fifo_errors.
- The count of transmitted packets reported by the forcedeth driver
reports pre-TSO (TCP Segmentation Offload) packet counts and not the
count of the number of packets sent on the wire. This change fixes
the forcedeth driver to report the correct count. Fixed the code by
copying the count stored in the NIC H/W to the value reported by the
driver.
- Count rx_drop_frame errors as rx_fifo_errors:
We see a lot of rx_drop_frame errors if we disable the rx bottom-halves
for too long. Normally, rx_fifo_errors would be counted in this case.
The rx_drop_frame error count is private to forcedeth and is not
reported by ifconfig or sysfs. The rx_fifo_errors count is currently
unused in the forcedeth driver. It is reported by ifconfig as overruns.
This change reports rx_drop_frame errors as rx_fifo_errors.

these manual updates. Main exception is rx_missed_errors which needs

When forcedeth module is unloaded, there exists a path that can lead
to mod_timer() after del_timer_sync(), causing an oops. This patch
short-circuits this unneeded path, which originates in
nv_get_ethtool_stats().
