Subject: [PATCH] Remove an unused variable from the Intel I/OAT DMA engine driver
Date: Sunday, September 16, 2007 - 5:31 pm

The 'u16 chanctrl' variable in 
drivers/dma/ioatdma.c::ioat_dma_free_chan_resources() is completely 
unused and gcc quite rightfully warns about it:

  drivers/dma/ioatdma.c:247: warning: unused variable 'chanctrl'

This patch removes the unused variable and silences the warning.
