Subject: [PATCH 10/30] usb: dwc2: gadget: Remove assigned but never used 'maxsize'
Date: Thu, 2 Jul 2020 15:46:05 +0100 [thread overview]
Message-ID: <20200702144625.2533530-11-lee.jones@linaro.org> (raw)
In-Reply-To: <20200702144625.2533530-1-lee.jones@linaro.org>
The value of 'maxsize' has not been checked since commit 729cac693eecf
("usb: dwc2: Change ISOC DDMA flow") back in 2018, so remove the set but
unused variable, which fixes the following W=1 kernel build warning:
drivers/usb/dwc2/gadget.c: In function ‘dwc2_gadget_fill_isoc_desc’:
drivers/usb/dwc2/gadget.c:885:6: warning: variable ‘maxsize’ set but not used [-Wunused-but-set-variable]
885 | u32 maxsize = 0;
| ^~~~~~~
