From: Vladimir Lypak <redacted> Interrupts on IPA v2.x have different numbers from the v3.x and above interrupts. IPA v2.x also doesn't support the TX_SUSPEND irq, like v3.0 Signed-off-by: Vladimir Lypak <redacted> Signed-off-by: Sireesh Kodali <redacted> --- drivers/net/ipa/ipa_interrupt.c | 11 ++++++++--- 1 file changed, 8 insertions(+), 3 deletions(-)
