Subject: spi: rspi: Make qspi_set_send_trigger() return "unsigned int"
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=cb76b1ca9174aa29d4c7c0f4aef113be203b600c;p=linux-beck.git

spi: rspi: Make qspi_set_send_trigger() return "unsigned int"

qspi_set_send_trigger() returns an unsigned value, so make it return
"unsigned int".
Update the loop variables qspi_trigger_transfer_out_int() to match the
above.
