Subject: [media] atmel-isi: Update error check for unsigned variables
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=e35abd4472c4ef235a8c3873d4b37a6b5fb1cb90;p=linux-beck.git

[media] atmel-isi: Update error check for unsigned variables

Checking '< 0' for unsigned variables always returns false. For error
codes, use IS_ERR_VALUE() instead.
