[PATCH] power: don't disable all cast qualifier warnings

[PATCH] power: don't disable all cast qualifier warnings

[Stephen Hemminger]

Only in one place does the power library need un-constify a pointer
and this can be done by casting to uintptr_t first. Better, to have
the warning enabled across the rest of the code.

Agree; disabling warnings should be avoided.
