Subject: debugfs: set no_llseek in DEFINE_DEBUGFS_ATTRIBUTE
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=895ce6c877cb0282a7dc2178f3643e6635716a2a;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

debugfs: set no_llseek in DEFINE_DEBUGFS_ATTRIBUTE

In DEFINE_DEBUGFS_ATTRIBUTE() macro, since we use nonseekable_open() to
open, we should use no_llseek() to seek, not generic_file_llseek().
