Subject: [PATCH] staging: vme_user: reorder NULL check after kzalloc in fake_crcsr_init
Date: Sat, 7 Feb 2026 21:55:02 +0000 [thread overview]
Message-ID: <20260207215502.1961-1-iprintercanon@gmail.com> (raw)
Move the NULL check for bridge->crcsr_kernel before its use in
fake_ptr_to_pci(). While fake_ptr_to_pci() is a simple cast that
handles NULL safely, using a value before validating it is a bad
pattern that static analyzers flag and could become a real issue
if fake_ptr_to_pci() changes in the future.
