Subject: platform/x86/siemens: simatic-ipc-batt: Simplify simatic_ipc_batt_remove()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=0580422560e2b93fe2e343d8438823824729a574;p=linux.git

platform/x86/siemens: simatic-ipc-batt: Simplify simatic_ipc_batt_remove()

Instead of unconditionally returning zero, let simatic_ipc_batt_remove()
return no value. This is a preparation to convert the drivers using this
function to struct platform_driver::remove_new().
