[ Upstream commit a7de1dea76cd6a3707707af4ea2f8bc3cdeaeb11 ]
A previous patch introduced a struct_group() in nvme_common_command to help stringop fortification figure out the length of the fields, but one function is not currently using them:
In file included from drivers/nvme/target/core.c:7: In file included from include/linux/string.h:254: include/linux/fortify-string.h:592:4: error: call to '__read_overflow2_field' declared with 'warning' attribute: detected read beyond size of field (2nd parameter); maybe use struct_group()? [-Werror,-Wattribute-warning] __read_overflow2_field(q_size_field, size); ^
Change this one to use the correct field name to avoid the warning.
