Subject: [PATCH][next] accel/habanalabs: remove redundant assignment to pointer 'input'
Date: Sat,  6 Jan 2024 12:42:13 +0000	[thread overview]
Message-ID: <20240106124213.51392-1-colin.i.king@gmail.com> (raw)

From: Colin Ian King <colin.i.king@intel.com>

The pointer input is assigned a value that is not read, it is
being re-assigned again later with the same value. Resolve this
by moving the declaration to input into the if block.

Cleans up clang scan build warning:
warning: Value stored to 'input' during its initialization is never
read [deadcode.DeadStores]
