Subject: [PATCH v3] staging: sm750fb: Replace comparisons with NULL and 0

Replace '(opt != NULL)' with '(opt)' and '(*opt != 0)'
with '(*opt != '\0')' to adhere to the coding standards.

Please ignore the other v3 patch I sent, I forgot to write
the change log in that patch. Apologies for any incovenienece
caused.

Changes in v2:
  - Update the commit message to reflect the changes better
  - Replace (*opt) with (*opt != '\0')

Changes in v3:
  - Remove unncessary spacing
