Subject: hwrng: exynos - remove redundant dev_err call in exynos_trng_probe()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=2273f42df1a52bb3aa827163e285528afbf7616c;p=linux.git

hwrng: exynos - remove redundant dev_err call in exynos_trng_probe()

There is a error message within devm_ioremap_resource
already, so remove the dev_err call to avoid redundant
error message.
