Subject: [PATCH v2] drm/nouveau/debugfs: Optimise data output in nouveau_debugfs_vbios_image()

Some characters should be put into a sequence.

* Thus print all data by the corresponding function “seq_write” at once.

* Return also the value from this function call.

* Omit a local variable which became redundant with this refactoring.


This issue was detected by using the Coccinelle software.
