Subject: media: nxp: imx8-isi: Replace udelay() with fsleep()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=2bab9442b85665c1f52062dca6a5623dffc18272;p=linux.git

media: nxp: imx8-isi: Replace udelay() with fsleep()

The ISI driver uses udelay() to wait for 300µs in a context where it can
sleep. Use fsleep() instead.
