drm/amdkfd: Fix error code sign for EINVAL in svm_ioctl()

[PATCH] drm/amdkfd: Fix error code sign for EINVAL in svm_ioctl()

Posted by Qianfeng Rong 4 weeks ago

Use negative error code -EINVAL instead of positive EINVAL in the default
case of svm_ioctl() to conform to Linux kernel error code conventions.

Fixes: 42de677f7999 ("drm/amdkfd: register svm range")
