Subject: spi: rspi: Drop variable "error" in qspi_trigger_transfer_out_in()
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=5d4db691ed978080435f4e5aad2ce707294a75b4;p=linux-beck.git

spi: rspi: Drop variable "error" in qspi_trigger_transfer_out_in()

Just use "ret" instead, for consistency with other similar functions.
