[PATCH] video: fbdev: mb862xx: mb862xx-i2c: delete now unused "int ret" variable

[Paul Gortmaker <paul.gortmaker@windriver.com>]

In commit 6b610e004baf ("video: fbdev: mb862xx: mb862xx-i2c: don't
print error when adding adapter fails") the users of the variable
were removed, resulting in:

drivers/video/fbdev/mb862xx/mb862xx-i2c.c: In function ‘mb862xx_i2c_init’:
drivers/video/fbdev/mb862xx/mb862xx-i2c.c:160:6: warning: unused variable ‘ret’ [-Wunused-variable]
  int ret;
      ^

...so here we remove the variable as well.

Fixes: 6b610e004baf ("video: fbdev: mb862xx: mb862xx-i2c: don't print error when adding adapter fails)"
