From 8e10fd851cb3e9723786703e3db45a2320b33a0e Mon Sep 17 00:00:00 2001 From: "Gustavo A. R. Silva" Date: Sun, 9 Jul 2017 18:14:38 -0400 Subject: media: marvell-ccic: constify i2c_algorithm structure Check for i2c_algorithm structures that are only stored in the algo field of an i2c_adapter structure. This field is declared const, so i2c_algorithm structures that have this property can be declared as const also. This issue was identified using Coccinelle and the following semantic patch: @r disable optional_qualifier@ identifier i; position p; @@ static struct i2c_algorithm i@p = { ... }; @ok@ identifier r.i; struct i2c_adapter e; position p; @@ e.algo = &i@p; @bad@ position p != {r.p,ok.p}; identifier r.i; @@ i@p @depends on !bad disable optional_qualifier@ identifier r.i; @@ static +const struct i2c_algorithm i = { ... }; Signed-off-by: Gustavo A.
