Super-IO accesses may fail on a system with no or unmapped LPC bus. Also, other drivers may attempt to access the LPC bus at the same time, resulting in undefined behavior. Use request_muxed_region() to ensure that IO access on the requested address space is supported, and to ensure that access by multiple drivers is synchronized. Fixes: ba224e2c ("hwmon: New PC87427 hardware monitoring driver") Reported-by:

Since every call to devm_kasprintf() in the switch statement is mostly the same, we can move all of the shared code outside and capture differencies with two helper variables. No functional change intended. Signed-off-by:
