Subject: [PATCH] platform/x86: thinkpad_acpi: use seq_puts() instead of seq_printf()
Date: Mon, 2 Feb 2026 12:52:11 -0800 [thread overview]
Message-ID: <20260202205214.18898-1-coby@bytemap.space> (raw)
checkpatch.pl reported warnings where seq_printf() was used for simple
strings with no format specifiers.
Replace these instances with seq_puts() to avoid the overhead of runtime
string parsing and to conform to kernel coding standards.
