5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Wang Ming <machel@xxxxxxxx>
[ Upstream commit 0266a2f791294e0b4ba36f4a1d89b8615ea3cac0 ]
The return value of the ksmbd_vfs_getcasexattr() is signed.
However, the return value is being assigned to an unsigned
variable and subsequently recasted, causing warnings. Use
a signed type.
