[PATCH] power: supply: Fix sizeof() mismatch

[Colin King]

From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

An incorrect sizeof() is being used, sizeof(psy->supplied_from) is not
correct, it should be sizeof(*psy->supplied_from).  This bug did not
cause any issues because it just so happens the sizes are the same.

Addresses-Coverity: ("Sizeof not portable (SIZEOF_MISMATCH)")
Fixes: f6e0b081fb30 ("power_supply: Populate supplied_from hierarchy from the device tree")
Signed-off-by: Colin Ian King <colin.king@xxxxxxxxxxxxx>
