Subject: [PATCH v1 1/2] iopoll: Introduce ioreadXX_poll_timeout() macros
Date: Thu, 30 Mar 2023 17:14:12 +0300	[thread overview]
Message-ID: <20230330141413.25569-1-andriy.shevchenko@linux.intel.com> (raw)

From: Olliver Schinagl <oliver@schinagl.nl>

There are users in the Linux kernel that would benefit from using
ioreadXX_poll_timeout() macros, such as ioread32_poll_timeout().
Introduce those macros.
