Subject: [PATCHv2 2/3] [media] s5p-jpeg: Fix compilation with COMPILE_TEST
Date: Tue, 09 Sep 2014 13:10:36 -0300	[thread overview]
Message-ID: <20140909131036.7265121f.m.chehab@samsung.com> (raw)
In-Reply-To: <540F1D11.9030400@samsung.com>

ERROR: "__bad_ndelay" [drivers/media/platform/s5p-jpeg/s5p-jpeg.ko] undefined!

That happens because asm-generic doesn't like any ndelay time
bigger than 20us.

Currently, usleep_range() couldn't simply be used, since
exynos4_jpeg_sw_reset() is called with a spinlock held.

So, let's use ndelay() instead.
