Subject: [PATCH v1 2/2] raw/ifpga/base: add argument to use untained variable
In fme_nios_spi_init(), passing tainted expression "fme->max10_dev"
to function "fme_get_board_interface" has risk. Add new arguemnt in function "fme_get_board_interface" to accept untainted variable.
Coverity issue: 367482
Fixes: 96ebfcf8125c ("raw/ifpga/base: add SPI and MAX10 device driver")
