Subject: dmaengine: print more meaningful error message
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=08baca4280d8abcf139fa8fec5b3de6f346efbae;p=openwrt%2Fstaging%2Fblogic.git

dmaengine: print more meaningful error message

error log for dma_channel_table_init() failure pointed a mere
"initialization failure", which is not very helpful message, so print
additional details like function name and error code.
