H A Drz-ssi.cdiff 7276d3f329c633340f3c539ce35ed254d2fe467b Tue Jan 25 07:24:55 CST 2022 Lad Prabhakar <prabhakar.mahadev-lad.rj@bp.renesas.com> ASoC: sh: rz-ssi: Use a do-while loop in rz_ssi_pio_recv()

Use a do-while loop while reading the samples from RX FIFO. The "done"
flag was only changed as an outcome of the last if-statement (last step)
in this entire procedure. This patch moves the condition from if
statement to while and drops the "done" variable for readability.

While at it, also drop the unneeded parentheses around runtime->dma_area.
