X-Git-Tag: v4.14-rc1~148^2~274

staging: pi433: Use matching enum types calling rf69_set_packet_format

This patch fixes the following four warnings found using sparse:

drivers/staging/pi433/pi433_if.c:211:9: warning: mixing different enum types
drivers/staging/pi433/pi433_if.c:211:9:     int enum optionOnOff  versus
drivers/staging/pi433/pi433_if.c:211:9:     int enum packetFormat
drivers/staging/pi433/pi433_if.c:211:9: warning: mixing different enum types
drivers/staging/pi433/pi433_if.c:211:9:     int enum optionOnOff  versus
drivers/staging/pi433/pi433_if.c:211:9:     int enum packetFormat
drivers/staging/pi433/pi433_if.c:268:9: warning: mixing different enum types
drivers/staging/pi433/pi433_if.c:268:9:     int enum optionOnOff  versus
drivers/staging/pi433/pi433_if.c:268:9:     int enum packetFormat
drivers/staging/pi433/pi433_if.c:268:9: warning: mixing different enum types
drivers/staging/pi433/pi433_if.c:268:9:     int enum optionOnOff  versus
drivers/staging/pi433/pi433_if.c:268:9:     int enum packetFormat

This is done calling the rf69_set_packet_format function using the
appropriate enum for the packetFormat argument.
