the comment is wrong as you avoid race with thread handler and not the
main ISR. The ISR runs in atomic context so you cant use a mutex but you
may do so with a thread handler

Will fix the comment in the next series.
+#define WLED_SHORT_DLY_MS 20
+#define WLED_SHORT_CNT_MAX 5
+#define WLED_SHORT_RESET_CNT_DLY_US USEC_PER_SEC

an empty line after defines would be better

Will add it in the next series.
+static int wled_configure_short_irq(struct wled *wled,
+ struct platform_device *pdev)
+{
+ int rc = 0, short_irq;

superfluous initialization of rc
Will remove the initialization in next series.
