[PATCH] ARM: bcm2835: remove unused __packet

[PATCH] ARM: bcm2835: remove unused __packet

[Ben Dooks]

The driver defines a variable called __packet but then never
uses it, and does not export it for others to use either. Fix
the warning about undeclared variable by removing it.

drivers/soc/bcm/raspberrypi-power.c:48:3: warning: symbol '__packet' was not declared. Should it be static?

PM folks: I'd be happy to see this go through your trees, but either way
is fine with me.

Since this is in drivers/soc, just include it in your cleanup branch for
arm-soc.

The patch looks good, but it's probably worth mentioning here that
this was intended to be the '__packed' attribute instead of a local
variable. The attribute is useless here, as the variables both
still get the default stack alignment, even if rpi_firmware_property
only requires byte-aligned data.
