[PATCH] staging: sm750fb: remove unnecessary goto

[Haasham Khan]

The error path in hw_sm750_crtc_set_mode() jumps to a label that
immediately returns ret. Return directly and remove the unnecessary
label.

[PATCH v2] staging: sm750fb: remove unnecessary goto

[Haasham Khan]

Return directly when setting the mode timing fails, rather than
jumping to a label that only returns ret. Return 0 on the successful
path.

Changes in v2:
- Return 0 on the successful path, as suggested by Dan Carpenter.
