Subject[PATCH 4.18 141/197] btrfs: Fix a C compliance issue
Date
4.18-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Bart Van Assche <bart.vanassche@wdc.com>

[ Upstream commit edf57cbf2b030781885e339f32e35a470d2f8eba ]

The C programming language does not allow to use preprocessor statements
inside macro arguments (pr_info() is defined as a macro). Hence rework
the pr_info() statement in btrfs_print_mod_info() such that it becomes
compliant. This patch allows tools like sparse to analyze the BTRFS
source code.

Fixes: 62e855771dac ("btrfs: convert printk(KERN_* to use pr_* calls")
