Subject: spi: topcliff-pch: Transform noisy message to dev_vdbg
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=342451df07109f865e6c108b7205e9738e814f3f;p=linux.git

spi: topcliff-pch: Transform noisy message to dev_vdbg

If during a SPI transfer with len larger than PCH_MAX_FIFO_DEPTH and the
IRQ handler happens to be called when the transmit FIFO is already empty,
and SPSR_FI_BIT is set consequently, the message
"spi_master spi32766: pch_spi_handler_sub : Transfer is not completed"
is spammed to the systemlog, because tx_index has already increased
further due to the next bytes to be written. This case is uncritical as
new bytes have already been written.
