Subject: staging: sm750fb: Refine code in set_current_gate().
X-Git-Tag: v4.10-rc1~148^2~370
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=cefc2fc61e1f5c80c6240634da01a4b846e9a6db;p=karo-tx-linux.git

staging: sm750fb: Refine code in set_current_gate().

The 'switch' statement in set_current_gate() had only two possible
scenarios, so it was replaced with an 'if' statement to make the code
shorter and easier to understand.
