Staging: iio: use the BIT macro in adc
This patch replaces bit shifting on:
0,1,2, and 3 with the BIT(x) macro.
Issue addressed by checkpatcg.pl.
This was done with the help of Coccinelle:
@r1@
identifier x;
constant int g;
@@
(
0<<\(x\|g\)
|
1<<\(x\|g\)
|
2<<\(x\|g\)
|
3<<\(x\|g\)
)
@script:python b@
g2 <<r1.g;
y;
@@
coccinelle.y = int(g2) + 1
@c@
constant int r1.g;
identifier b.y;
@@
(
-(1 << g)
+BIT(g)
|
-(0 << g)
+ 0
|
-(2 << g)
+BIT(y)
|
-(3 << g)
+(BIT(y)| BIT(g))
)
