The first 9 patches in this series are coding style changes, including a number of patches to remove the "typedef" directive from a number of data structure definitions. This clears the checkpatch warning about defining new data types in the code. The last patch in the series, however, changes the data type of a member variable from a u8 to an enumerated type. Generally in C an enumerated type is implemented by the compiler as an int, but can be changed by compiler directives. Either way the member variable will most probably have its size changed by this patch. I don't think that the structure is mapped to hardware or physical memory location, but is allocated and populated in the rtl8192_usb_probe() function in the file r8192U_core.c. Given that allocation/population I don't think that the size of the member variable is of run time significance, bar the slight increase in size of the overall structure. The reason for doing this is to enable the compiler's checking of assignments to the variable defined as an enumerated type. The alternative is to leave the variable as a u8 and remove the enumerated type, replacing it with #define definitions of the possible values. I raised this issue on the kernel newbies mailing list and of the two alternatives enumerated type won out. _______________________________________________ devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxx http://driverdev.linuxdriverproject.org/mailman/listinfo/driverdev-devel
