From: Martin Kaiser Date: Mon, 23 Jan 2023 20:53:20 +0000 (+0100) Subject: staging: r8188eu: we use a constant number of hw_xmit entries X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=11617b77ad730903dc9a9cc659656b0ade03ef3e;p=linux.git staging: r8188eu: we use a constant number of hw_xmit entries struct xmit_priv contains a pointer to an array of struct hw_xmit entries. xmit_priv's (ill-named) hwxmit_entry component stores the size of this array, i.e. the number of hw_xmit entries that are used. The array size is constant, it's initialised to HWXMIT_ENTRY and never updated. Simplify the code accordingly. Remove hwxmit_entry, do not pass the array size as a function parameter and use HWXMIT_ENTRY in the code that handles the array.
