None of the current instances of struct w1_family_ops in the kernel is modified. Constify these to let the compiler put them in read-only memory.
The first patch changes the fops field in w1_family struct to a pointer to const and makes a local variable a pointer to const to avoid a compiler warning. This patch is a prerequisite for the second and third patches which constifies the static structs in drivers in w1 and power. These changes was done with coccinelle (details in the commit messages).
With these changes applied, all instances of struct w1_family_ops in the kernel are const.
Build-tested on x86 allmodconfig.
Rikard Falkeborn (3): w1: Constify struct w1_family_ops w1: Constify static w1_family_ops structs power: supply: Constify static w1_family_ops structs
