Subject: msi-wmi: Use enums for scancodes
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=b0d3bb53beaba866ce80424fb512b1669ed88da0;p=openwrt%2Fstaging%2Fblogic.git

msi-wmi: Use enums for scancodes

Use enums for consecutive scancodes, rename key names from MSI_WMI_* to
MSI_KEY_* and use tabs for whitespace in msi_wmi_keymap.
