Subject: spi: core: Do not mangle error code from kthread_run()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=98a8f5a0538fe1a02a6a73a3451f1c093e30bdfc;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

spi: core: Do not mangle error code from kthread_run()

kthread_run() could return ERR_PTR(-EINTR) from kthread_create_on_node().
Return the actual error code in spi_init_queue() instead of mangling it to
-ENOMEM.
