Judging from a few Outreachy patches that have hit my inbox, snprintf() is

->poll() functions should return __poll_t, but the fieldbus
core's poll() does not. This generates a sparse warning.
Fix the ->poll() return value, and use recommended __poll_t
constants (EPOLLxxx).

The regmap's context (stored as 'void *') consists of a pointer to
__iomem. Mixing __iomem and non-__iomem addresses generates
sparse warnings.
Fix by using __force when converting to/from 'void __iomem *' and
the regmap's context.

What if I create a separate structure for the regmap context ?
struct anybus_regmap_context {
void __iomem *base;

Then just store the base pointer inside the struct,

Basically because it creates a regmap which accesses __iomem memory,

As a pleasant side-effect, sparse warnings now disappear.
