Subject: [PATCH 04/13] procinterrupts: Fix IRQ name parsing on certain arm64
|
|
SoC
|
|
|
|
On arm64 SoCs like TI's K3 SoC and few other SoCs, IRQ names don't get
|
|
parsed correct due to which they end up being classified into wrong
|
|
class. Fix this by considering last token to contain IRQ name always.
|
|
|
|
Eg.: /proc/interrupt
|
|
|
|
cat /proc/interrupts
