#     powerpc/85xx: Get twr_p102x to compile again
#     
#     With CONFIG_QUICC_ENGINE enabled and CONFIG_UCC_GETH + CONFIG_SERIAL_QE
#     disabled we have an unused variable (np). The code won't compile with
#     -Werror.
#     
#     Move the np variable to the block where it is actually used.
