| Subject: usb: musb: Modify the "HWVers" register address |
| |
| From: Xingxing Luo <xingxing.luo@unisoc.com> |
| |
| commit 6658a62e1ddf726483cb2d8bf45ea3f9bd533074 upstream. |
| |
| musb HWVers rgister address is not 0x69, if we operate the |
| wrong address 0x69, it will cause a kernel crash, because |
| there is no register corresponding to this address in the |
| additional control register of musb. In fact, HWVers has |
| been defined in musb_register.h, and the name is |
| "MUSB_HWVERS", so We need to use this macro instead of 0x69. |
| |
| Fixes: c2365ce5d5a0 ("usb: musb: replace hard coded registers with defines") |
