Subject: [PATCH] spi: signedness bug in qspi_trigger_transfer_out_int()

We need "ret" to be unsigned for the error handling to work.  The
signedness of "i" and "n" don't matter but qspi_set_send_trigger()
returns an int so I've changed them to int as well.

Fixes: 4b6fe3edcbba ('spi: Using Trigger number to transmit/receive data')
