From e020f604abaa6da9b7d579d9d73ffaf37072f520 Mon Sep 17 00:00:00 2001 From: Michael Kelley Date: Wed, 14 Jan 2026 09:01:12 -0800 Subject: [PATCH] mshv: Store the result of vfs_poll in a variable of type __poll_t vfs_poll() returns a result of type __poll_t, but current code is using an "unsigned int" local variable. The difference is that __poll_t carries the "bitwise" attribute. This attribute is not interpreted by the C compiler; it is only used by 'sparse' to flag incorrect usage of the return value. The return value is used correctly here, so there's no bug, but sparse complains about the type mismatch. In the interest of general correctness and to avoid noise from sparse, change the local variable to type __poll_t. No functional change.
