Subject: [PATCH][next] brcmfmac: Replace one-element array with flexible-array member
Date: Thu, 2 Feb 2023 19:29:47 -0600 [thread overview]
Message-ID: <Y9xjizhMujNEtpB4@work> (raw)
One-element arrays are deprecated, and we are replacing them with flexible
array members instead. So, replace one-element array with flexible-array
member in struct brcmf_tlv.
This helps with the ongoing efforts to tighten the FORTIFY_SOURCE
routines on memcpy() and help us make progress towards globally
enabling -fstrict-flex-arrays=3 [1].
This results in no differences in binary output.
