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)) ) Signed-off-by: Haneen Mohammed <hamohammed.sa@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
