Subject: [PATCH][next] can: etas_es58x: Replace zero-length array with DECLARE_FLEX_ARRAY() helper
Date: Mon, 29 Aug 2022 16:50:59 -0500 [thread overview]
Message-ID: <Yw00w6XRcq7B6ub6@work> (raw)
Zero-length arrays are deprecated and we are moving towards adopting
C99 flexible-array members, instead. So, replace zero-length array
declaration in union es58x_urb_cmd with the new DECLARE_FLEX_ARRAY()
helper macro.
This helper allows for a flexible-array member in a union.
