staging: sm750fb: Rename oScreen to o_screen in lynxfb_crtc
The struct lynxfb_crtc has a member named oScreen. This name is
CamelCase and is frowned upon. This commit renames it to o_screen
and makes the necessary changes for the module to build.
This change also fixes the following checkpatch CHECKs:
CHECK: Avoid CamelCase: <oScreen>
138: FILE: sm750.h:138:
+ int oScreen; /* onscreen address offset in vidmem */
CHECK: Avoid CamelCase: <oScreen>
178: FILE: sm750.c:178:
+ base = par->crtc.oScreen;
