[PATCH 10/30] usb: dwc2: gadget: Remove assigned but never used 'maxsize'

From: Lee Jones
Date: Thu Jul 02 2020 - 10:49:02 EST


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 âdwc2_gadget_fill_isoc_descâ:
drivers/usb/dwc2/gadget.c:885:6: warning: variable âmaxsizeâ set but not used [-Wunused-but-set-variable]
885 | u32 maxsize = 0;
| ^~~~~~~
