X-Git-Tag: v2.6.25-rc2~8^2~5
X-Git-Url: https://openfabrics.org/gitweb/?a=commitdiff_plain;h=5163dc1a645bc9ed7984fa484f1a77378c166d23;p=~emulex%2Finfiniband.git

IB/mthca: Convert to use be16_add_cpu()

replace:

	big_endian_variable = cpu_to_beX(beX_to_cpu(big_endian_variable) +
						expression_in_cpu_byteorder);

with:

	beX_add_cpu(&big_endian_variable, expression_in_cpu_byteorder);

Generated with a semantic patch.
