0b9e69e1a1 net: dm9051: Make remove() callback a void function 
Changes introduced since the merge window in the spi subsystem and
available at:

   https://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi.git tags/spi-remove-void

make the remove() callback for spi return void rather than int, breaking
the newly added dm9051 driver fail to build.  This patch fixes this
issue, converting the remove() function provided by the driver to return
void.

8c16baa51b net: Fix an ignored error return from dm9051_get_regs() 
The return from the call to dm9051_get_regs() is int, it can be
a negative error code, however this is being assigned to an unsigned
int variable 'ret', so making 'ret' an int.

Eliminate the following coccicheck warning:
./drivers/net/ethernet/davicom/dm9051.c:527:5-8: WARNING: Unsigned
expression compared with zero: ret < 0
