video: Add missing annotation for cyber2000fb_enable_ddc() and cyber2000fb_disable_ddc()
Sparse reports warnings at cyber2000fb_enable_ddc()
and cyber2000fb_disable_ddc()
warning: context imbalance in cyber2000fb_enable_ddc()
- wrong count at exit
warning: context imbalance in cyber2000fb_disable_ddc()
- unexpected unlock
The root cause is the missing annotation at cyber2000fb_enable_ddc()
and cyber2000fb_disable_ddc()
Add the missing __acquires(&cfb->reg_b0_lock) annotation
Add the missing __releases(&cfb->reg_b0_lock) annotation
