Subject: arm64: fix show_data fallout from KERN_CONT changes
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=ebe8b41ef6a194c8d1d3184f4197019f8c5146af;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

arm64: fix show_data fallout from KERN_CONT changes

The log format printed by show_data is illegible due to printk change
"commit 4bcc595ccd80decb ("printk: reinstate KERN_CONT for printing
continuation lines")".

The output is like:

[   32.669703]  b01f7cd0
[   32.669706]  ffffffc0

To fix this, use pr_cont() instead of the printk() to print
continuing lines.
