[PATCH 5.10.y-cip 10/11] spi: spi-rspi: Drop redeclaring ret variable in qspi_transfer_in()

Lad Prabhakar

commit 1d734f592e1a1d41af80e90001d109cec1c98fb4 upstream.

"ret" variable is already declared in qspi_transfer_in() at the
beginning of function, drop redeclaring ret in the if block, fixing

spi-rspi.c: In function ‘qspi_transfer_in’:
spi-rspi.c:838:7: warning: declaration of ‘ret’ shadows a previous local
838 | int ret = rspi_dma_transfer(rspi, NULL, &xfer->rx_sg);
| ^~~
spi-rspi.c:835:6: note: shadowed declaration is here
835 | int ret;
