Subject: [PATCH v1 1/2] raw/ifpga/base: use untained variable as argument
In fme_spi_init(), passing tainted expression "fme->max10_dev"
to function "intel_max10_device_remove" has risk. Untainted variable "max10" should be used.
Coverity issue: 367480
Fixes: 96ebfcf8125c ("raw/ifpga/base: add SPI and MAX10 device driver")
