[U-Boot] [PATCH v3] net: Use ARRAY_SIZE at appropriate places
Axel Lin

Wed Jul 3 05:24:18 CEST 2013
Use ARRAY_SIZE instead of having similar implementation in each drivers.
The NUMELEMS defined in drivers/net/npe/include/IxOsalTypes.h is not used
at all, so this patch removes it instead of converting it to use ARRAY_SIZE.

v2: Fix checkpatch issues. (abandoned)
v3: Modified from v1, because v2 makes the patch bigger.
And using tab (which takes 8 spaces) as indent makes the code looks odd
because the whole file uses 4 spaces as indent.
Note, the checkpatch issue is not introduced by this patch itself, it's
because original source code does not pass checkpatch at all.
Address Marek's comment:
Remove NUMELEMS in drivers/net/npe/include/IxOsalTypes.h
because it is not used at all.
