Subject: [PATCH AUTOSEL 6.14 19/27] HID: lenovo: Fix to ensure the data as __le32 instead of u32

From: Vishnu Sankar <vishnuocv@...il.com>

[ Upstream commit d6ea85f8371b99c1d3a90ee4e2fb1a648f8d71d3 ]

Ensure that data is treated as __le32 instead of u32 before
applying le32_to_cpu.
This patch fixes the sparse warning "sparse: cast to restricted __le32".
