Subject: [PATCH v1 1/1] cpuidle: Update header inclusion
Date: Mon, 24 Nov 2025 21:57:52 +0100 [thread overview]
Message-ID: <20251124205752.1328701-1-andriy.shevchenko@linux.intel.com> (raw)
While cleaning up some headers, I got a build error on this file:
drivers/cpuidle/poll_state.c:52:2: error: call to undeclared library function 'snprintf' with type 'int (char *restrict, unsigned long, const char *restrict, ...)'; ISO C99 and later do not support implicit function declarations [-Wimplicit-function-declaration]
Update header inclusions to follow IWYU (Include What You Use)
principle.
