Subject: [PATCH 0/4] Explicitly deny IRQ0 in the libata drivers
Date: Sun, 21 Mar 2021 21:50:36 +0300	[thread overview]
Message-ID: <2e552c36-84a5-a642-a8f0-1395f77a1a6a@omprussia.ru> (raw)

Here are 4 patches against the 'master' branch of the Jens Axboe's 'linux-blobk.git'
repo plus the 'pataep_93xx' driver patch re-posted yesterday.  The affected drivers
use platform_get_irq() which may return IRQ0 (considered invalid, according to Linus)
that means polling when passed to ata_host_activate() called at the end of the probe
methods. I think that the solution to this issue is to explicitly deny IRQ0 returned
by platform_get_irq()...

[1/4] pata_bk3710: deny IRQ0
[2/4] pata_ep93xx: deny IRQ0
[3/4] pata_ftide010: deny IRQ0
[4/4] pata_imx: deny IRQ0
