[PATCH -next] leds: fix LEDS_LP55XX_COMMON dependency and build errors

[Randy Dunlap]

From: Randy Dunlap <rdunlap@infradead.org>

Make LEDS_LP55XX_COMMON depend on I2C to fix build errors:

leds-lp55xx-common.c:(.text+0x9d): undefined reference to `i2c_smbus_read_byte_data'
leds-lp55xx-common.c:(.text+0x8fc): undefined reference to `i2c_smbus_write_byte_data'

These errors happened when I2C=m and LEDS_LP55XX_COMMON=y, so
prevent that from being possible.

git is unhappy with your patch for some reason:

Applying: leds: fix LEDS_LP55XX_COMMON dependency and build errors
error: corrupt patch at line 14
Patch failed at 0001 leds: fix LEDS_LP55XX_COMMON dependency and build
errors
The copy of the patch that failed is found in: .git/rebase-apply/patch
When you have resolved this problem, run "git am --continue".
If you prefer to skip this patch, run "git am --skip" instead.
To restore the original branch and stop patching, run "git am
--abort".

I somehow applied it by hand and pushed out. Thanks!
