Subject: [PATCH 0/5] bnx2x: Remove function casts
In order to make the entire kernel usable under Clang's Control Flow
Integrity protections, function prototype casts need to be avoided
because this will trip CFI checks at runtime (i.e. a mismatch between
the caller's expected function prototype and the destination function's
prototype). Many of these cases can be found with -Wcast-function-type,
which found that bnx2x had a bunch of needless (or at least confusing)
function casts. This series removes them all.

bnx2x: Drop redundant callback function casts
bnx2x: Remove read_status_t function casts
bnx2x: Remove config_init_t function casts

bnx2x: Remove hw_reset_t function casts
