Subject: [PATCH 1/6 v2] mmc: meson-gx-mmc: Fix platform_get_irq's error checking
Date: Sat, 18 Nov 2017 15:03:43 +0530 [thread overview]
Message-ID: <130df0c2c60ed6a0f460b68c586cc0a4167aed0b.1510997223.git.arvind.yadav.cs@gmail.com> (raw)
The platform_get_irq() function returns negative if an error occurs.
zero or positive number on success. platform_get_irq() error checking
for zero is not correct.
Signed-off-by: Arvind Yadav <arvind.yadav.cs@gmail.com>

changes in v2 :
Add failure case '<= 0' instead of '< 0'. IRQ0 is not valid.
