Subject: spi: spi-nxp-fspi: Fix a NULL vs IS_ERR() check in probe
Git-commit: 1a421ebab6bb5bf65001743ba9fef48e94fb345a
Patch-mainline: v5.7-rc1
References: jsc#SLE-16106
The platform_get_resource_byname() function returns NULL on error, it
doesn't return error pointers.
Fixes: d166a73503ef ("spi: fspi: dynamically alloc AHB memory")
