Subject: [PATCH v2] Staging: pi433: Fix the position of brace after if
Fix the position of the brace after if when it is on the next line.
Done using the following semantic patch by coccinelle.

@script: python r2@

l1 = int (p1[0].line)
l2 = int (p2[0].line)
c1 = int (p1[0].column_end)
c2 = int (p2[0].column)
if l1 == l2 and c1+1 == c2:
