Subject: [PATCH v2 1/2] staging: r8188eu: Use sizeof dereferenced pointer in kzalloc()
Date: Tue, 8 Feb 2022 19:04:25 +0100 [thread overview]
Message-ID: <20220208180426.27455-2-fmdefrancesco@gmail.com> (raw)
In-Reply-To: <20220208180426.27455-1-fmdefrancesco@gmail.com>
checkpatch.pl emits the following warning:
CHECK: Prefer kzalloc(sizeof(*pcmd)...) over kzalloc(sizeof(struct cmd_obj)...)
+ pcmd = kzalloc(sizeof(struct cmd_obj), GFP_KERNEL);
CHECK: Prefer kzalloc(sizeof(*psetkeyparm)...) over kzalloc(sizeof(struct setkey_parm)...)
+ psetkeyparm = kzalloc(sizeof(struct setkey_parm), GFP_KERNEL).
According to the above "CHECK[S]", use the preferred style in the two kzalloc()
of rtw_set_key().
