Subject: [PATCH 2/2] fpga: dfl: omit unneeded casts of u64 values for dev_dbg()
Date:   Tue,  4 Jul 2023 22:54:51 -0400
Message-Id: <0cffb04a207a98148c61f512aa4dc90880e51251.1687301688.git.peter.colberg@intel.com>

Omit unneeded casts of u64 values to unsigned long long for use with
printk() format specifier %llx. Unlike user space, the kernel defines
u64 as unsigned long long for all architectures; see commit 2a7930bd77fe
("Documentation/printk-formats.txt: No casts needed for u64/s64").

These changes are cosmetic only; no functional changes.
