Subject: [PATCH] power: supply: cpcap-battery: make array cpcap_battery_irqs static, shrinks object size

From: Colin Ian King <[email protected]>

Don't populate the array cpcap_battery_irqs on the stack but instead
make it static. Makes the object code smaller by 99 bytes:

Before:
text data bss dec hex filename
13673 2448 0 16121 3ef9 cpcap-battery.o

After:
text data bss dec hex filename
13510 2512 0 16022 3e96 cpcap-battery.o

(gcc version 8.2.0 x86_64)
