x25: remove redundant pointer dev
Pointer dev is being assigned a value that is never used, the assignment and the variable are redundant and can be removed. Also replace null check with the preferred !ptr idiom. Cleans up clang scan warning: net/x25/x25_proc.c:94:26: warning: Although the value stored to 'dev' is used in the enclosing expression, the value is never actually read from 'dev' [deadcode.DeadStores] Signed-off-by: Colin Ian King <colin.i.king@gmail.com> Link: https://lore.kernel.org/r/20220508214500.60446-1-colin.i.king@gmail.com Signed-off-by: Paolo Abeni <pabeni@redhat.com>
